Finding the Slope of a Line

[touchscream56789]

Im guessing yes but I thought I would just ask anyway

[touchscream56789]

if you know what I mean

[touchscream56789]

Do you always have to simplify the slope once you have it?

[TheAkolade26]

you the best man, my math teacher teaches stuff fast and sometimes, i don't get it especially this topic but when i watched this video, i used it to study for my test and i got 102.77% on it. my mom and my teacher were so surprised they asked "how did u get it so fast" becuz they knew i was having problems with the topic. i answered. Patrick helped.

[patrickJMT]

@TheAkolade26 that is super awesome : ) congrats on your great score!! keep up the hard work for sure

[ChinoPR001]

I'm surprised that he made dis vid like what 3 years ago? And theres still comments every day, patrick, dam bro, ur doing a great job:)

[patrickJMT]

@ChinoPR001 math aint goin' out of style, yo

[xXBrooke96Xx]

Can you please come down to Australia and take my maths class!? My teacher just taught us this and she taught it in such a complicated way and we've been doing this sort of stuff for about 3 weeks now and i havent understood it and now i understand it within a couple of minutes! THANKYOUTHANKYOUTHANKYOU! i have a maths test tomorrow so im using your videos to teach me eveything my teacher 'taught' me. :D

[patrickJMT]

@xXBrooke96Xx good luck on the test!

[ThisIsTheRenegade]

So well explained, especially when lecturers use a lot of complex lingo, thanks :)

[patrickJMT]

@ThisIsTheRenegade glad i could help : )

[Tajul420]

thanks brother,we need people like you in the world who like to help the man kind, your videos are helping huge students like me who are thankful to you.

[bigtymplaya9]

Awesome!

[trazz7242]

how could anybody dislike such a video? these idiot people dnt hav "common sense"

[Assassin122112]

You taught me more about this in this six minute video than my 8th grade math teacher did in 17 days of school. And yes I do pay attention. Thank you! :-)

[ShockSword]

Thanks a lot. I had a student teacher for this chapter in math. I couldn't adjust to how he taught the class and I didn't understand what he was trying to say. :3

[cocanutcraZe]

what if your fraction is negative like -6/4? would you just do the reciprocal?

[rxairport]

hello i have a question:

does it matter which point two points you choose or are the points always given??

[ClockPop]

I get the rise part, but how do you know how many units you're suppose to run?

[xXLunarEclipse896Xx]

I wish you were my Algebra teacher. If I had watched your videos during the first semester, I wouldn't have failed those Algebra finals. >.>

[halomasterchief14]

why is the point-slope formula neccessary to remember?, What does it show that the slope intercept formula doesn't? y-y1=m(x-x1) <-- what does this have to do with slopes, how do I read it?

[princesssaph]

this is great! but how do you find the slope of a line when y+4=3 ?!?!?

[Prank6767]

U rock dude!!!

[YJ4]

Very helpful, thank you. Math is much easier when I learn by watching a video by myself. Thanks again to you and of course the invention of YouTube (and video technology in general!)

[h3sl]

u said it doesn't matter if we consider any of the points as x1 y1 cuz we will get the same answer ( negative ) as the slope of a line goes down .. am talkin about the 2nd example ,, but matter of fact it will make a differences cuz it will give me a positive value !! can u explain that please , am lil bit confuse

[patrickJMT]

@h3sl you are doing something wrong somewhere

[h3sl]

ops , u are rite .. am sorry , i should question my power of observation next time ... thnx again

[patrickJMT]

@h3sl feel free to ask questions : ) that is part of it!

[TheTonylearner]

I wish to say "thank you" for your wonderful video. You were clear, to the point, and your pacing was comfortable. Bravo!

[bamarine75]

when you found your new slope of -8 0ver +7, what does the new line look like?

[sgwars525671]

me too thanks for taking the time out to learn us this many thanks again great stuff...why are you having problemswith breathing in through your nose ?

[desertfox3638]

can you come replace my math teacher shes been trying to teach this like the whole year but i tune out abou 30 seconds in, and i get on youtube and learn it 6 mins

Great video helped a bunch thank you

[musicalbeast95]

i looooove youtube for its fantastic algebra help videos:)

[Raven4567890]

I don't get why the slope is 1/2

[gogreenlover12]

just like the first minute i didnt understand! :/

[ch0colatefreak]

omg i finallt get this ...evry other person who taught it on utube freakin was too confusing and dint answer the dam quetions i had.... thanks sooooo much

[Coleybear60]

thanks im doing test corrections and i didnt know how to do this at all u saved my @55 thanx again

[margieisepic]

If my math teacher explained things the way you do I would probably like math a lot more.

[SamsungGX20]

Why's the slope 1/2? You didn't say why it is.

[penguinrancher]

2/4 is the same as 1/2 he just simplified it.

[ch0colatefreak]

@penguinrancher hey can i ask u a question cuz i dont get this 1 thing du u noe wat to du if they DONT give u the points and how u plot the points...do u jus randomly pick...cuz i noe u cant do that ull get diffent anwers all the time plz help i hav math test this monday!!!!!!!

[paddyshieldsy87]

you are the main man! really clearly explained.. top dog!

[WBartok77]

I alwas thought that this was hard , but the way you explained it make it so much easier , thank you I finally got it :-D

[edae13]

dude you helped me out soo much 2012 baby

[purplecurtisimo]

YOURE AWESOME

[Lastscionz]

Thank you, I have a final and this shit is all over the god damn place(no imaginary numbers either).

[leaundriea]

can you or someone show me how to work this problem out. find the slope of a line: y=x-3

and another one y=-2x+3  please

[swatslayer88]

@ leaundriea the slope in ur first equation is positive one....and in ur second equation is -2.......becoz u dont have to divide ur y coz it is already one...u know what i mean....i hope that helped....lol

[cardcutter]

i need to figure find the x and y as well as the slope for y+8x=9 please please help

[Narutoguy89]

now i just need to know how to put this in a equation

[SuperWeinerCreator]

Thank you soooo much ^-^ This helped a lot for my math O.O *happy*

[Hq3d]

thanks i got it now

my teacher is terrible don't get a thing she says

[Harry1234567Potter]

thanks soo much this helped me so much :)

[hoopz2598]

the only thing i don't get is...how do you know which number is y2 and which is y1? You can't just choose because it changes the answer.

[gaildelo]

As long as one point is (x1,y1) and the other is (x2,y2) you will get the same answer. You can choose either point for (x1,y1) and the answer will turn out the same. Just watch your signs.

[Kenji314159]

@hoopz2598 let me explain that. It doesn't matter which point is the second one and which is the first one. It just has to stay that way for the x and the y coordinate. An example: P1(1,2) and P2(7,3), the slope m= (3-2)/(7-1) = 1/6. Ok, and now the other way arround: P1(7,3) and P2(1,2), the slope m = (2-3)/(1-7) = -1/-6 = 1/6. As you see, negative divided trough negative = positive.

[leftocastpunx83]

@hoopz2598 it doesn't matter which point is 1 and which is 2 as long as you use corresponding points. so whichever you choose as y1 you must use the corresponding x as your x1 and likewise for y2 and x2.

[TwistedPizzaDude]

@hoopz2598 you probably already got someone to respond, but the coordinate closer to the Y-Scale will be your x1 and y1! :)

[DarklightALBANIA]

@hoopz2598 He answers your question at 4:50

[darkp93]

THx man for your help!

[sexy2lvrn]

I have a question: if you have found a slope of a line using m=y-y / x-x what if your answers comes out negative meaning like for example -4/-9 does that mean you need to change the slope to 4/9?

[patrickJMT]

yes: a negative divided by a negative is positive!

[sexy2lvrn]

thank you so much...your teaching is awesome and understanding..peaceandluv

[cheer4life12321]

you are wayyyyyyy better than my teacher!!!! i thought i was gunna be dommed for finals. Thank you so much! =D

[HunterJumper1333]

omigoshh

thank you ^-^

I have an exam tomorrow and completely forgot how to do it haha

very helpful

[bigphil006]

Superb... Very helpful

[619Moneyman]

can you tell me what is

y=-5x -1

please i need it quick for hw

[tomato332]

Thanks for this video. Helped me alot and we call the slope "m" because thats the beginning letter for the greek word slope i think.

[Luineancaion]

Could this video also be tagged with 'gradient', took a while to find. :-) Great stuff as always! This stuff really makes maths fun. Think I'll take it up as a hobby.

[TheDuskMar]

I was in Algebra I, just learning how to find slopes. I learned the derivative formula (lim n->0 ( f ( x + n ) - f ( x ) ) / n ) before the y/x (rise over run) and I always got the slope right. My teacher was astounded at how I used the derivative. She gave me a nice little curve to solve and I even got that correct (I distinctly remember it as 2x^3 - x^2 + x + 1 ) which would be 6x^2 - 2x + 1 =]

Thanks for teaching me the derivative formula, and also the slope.

[tuttifruitysummerlov]

you multiply by 10 so you don't have to have decimals.

[zelvhic]

Why is it you multiply both side by 10?

[animeluver296]

thank u man! u explain better than my teacher.i thought i was doomed.thx^-^

[2846weed]

thanks
