Question

Change -3x+3y=9 into slope intercept form

Answer 1

y = x + 3

Explanation:

-3x + 3y = 9

3y = 9 - 3x

/3 /3 /3

y = x + 3

Answer 2

To convert to slope-intercept form, we need to get the y by itself.

First add 3x to both sides to get 3y = 3x + 9.

I put the x term first because in slope-intercept form or y = mx + b form,

the x term will always come before the constant term.

Now divide both sides by 3 to get y = x + 3.
