In this lesson, students learn to convert a linear equation to slope-intercept, or y = mx + b form, by getting y by itself on the left side of the equation. For example, to convert the equation x -- 3y = -12 to y = mx + b form, the first step is to subtract x from both sides to get --3y = -x -- 12. Notice that the x term is positioned before the number on the right side of the equation so that the equation will eventually match up with y = mx + b form. Next, divide both sides by --3 to get y = 1/3 x + 4. Now the problem is in y = mx + b form, with m = 1/3 and b = 4, and the line can be graphed using the slope and y-intercept.

Your sitting in class and you dont get it.

You go to your friends for help but you still dont get it.

You go to your parents for help but you still dont get it.

You go to youtube and you finally get it.

@Hermiix36 because he divided 6 by 3

[Likabavvs]

y2-y1/x2-x1



[Hermiix36]

im crying because i dont know where you got two from

[Likabavvs]

@MightyDawq To find the b value you have to have the m,y and x value

for example

m=2

y=5

x=-6

so you would do: 5=2(-6)+b

5=-12+b

5+12=b

17=b

FINAL ANSWER: y=2x+17

I have an exam Tom do thank but u dindnt answer what I was looking for

[MightyDawq]

can someone please tell me how u can find "b" value of y=mx+b if u know the slope? please help i got exam tomorrow

[iamkaylaforlife]

I've got a test tomorrow and I'm up at 12 try a understand this.

[LZnathalie]

exam is in 8 hours...youtube you life saver!
