How do you find the slope intercept form of this equation?

3x-8y=-32

The first thing you have to remember is y=mx+b

3x-8y=-32

-3x - 3x

-8y=-3x-32

Divide - 8 for everything.

y = 3/8x + 4

If you are wondering why the answers aren't negative, remember that when you divide a negative by another negative, it becomes positive.
