-3 = x/-9

To make this easier, I'll put it in normal numbers

(-3 = x/-9) -1

3 = x/9

Multiply both sides by nine to take out the division.

27 = x

Hope that this helped!

Shkiper50 [21]
Y=2x+0. The two would be next to the x, because that represents the slope. And it would plus zero, because zero is the initial value, since it's passing through the origin.
