@MonstersNightmare Oh and I forgot to mention Y=MX + B when M doesn't have a numerator and denominator but it looks something like, y=4x+3.
-
I had notes that talked about finding Y by changing X to a 0 and finding X by changing Y to the value of 0. At first I thought it was for coordinates, but instead they used to form a line it looks like. Is that just another option? Also, I have seen notes with B having a fraction, and M having a fraction, but instead of rise over run, it looks like the dot is the fraction value. I'm getting too confused. :-(

Thank you sooo much! I was soo stuck on this. I also like how you put a lot of examples!

@picrustable OMG i have a math test tomorrow on this stuff ...and this helped me soooooo much....thank you!!!!! your the best

Math teacher raps y=mx+b to Chamillionaire's Ridin Dirtyby wiesse71,550 views
okay well my equation is y=.29x+9
so how do i get .29 into a whole number?
MrBlackDeath69 2 years ago
0.29 means 29 hundredths... so a fraction for 0.29 would be
29/100
(This would not be a whole number because it is your slope.)
It works for any decimal, just determine the place value of the last number of the decimal.
Okay, well, there you go. :-)

@picrustable so i would rise 29 and run 100?
MrBlackDeath69 2 years ago
If your equation is y = 0.29x + 9, that would be a yes. 29/100 doesn't reduce. Rather icky equation. I suggest changing your x and y values to 10's and not 1's so it would fit on your graph.

Strange equations like this are not so nice for beginning students. You are more likely to see this type of equation in a business class. Hope that helps.

@picrustable so should I end up with this
y= 20/100 + 900
or do I just leave the 9 as a nine?
MrBlackDeath69 2 years ago
MrBlackDeath69
Leave the 9. I would reduce the fraction so that it is easy to see rise over run.
