Question

Write the linear equation -3x+9y=-27

Answer 1

Hello!

To write this in slope intercept form we have to solve for y.

Add 3x to both sides.

9y=-27+3x

Divide both sides by 9

y=-3+1/3

Rearrange into slope intercept form.

y=1/3x-3

I hope this helps!

Answer 2

$y=mx+b\\\\-3x+9y=-27\ \ \ |+3x\\\\9y=3x-27\ \ \ |:9\\\\y=\dfrac{3}{9}x-\dfrac{27}{9}\\\\y=\dfrac{1}{3}x-3$
