-2x + 3y > 9
3y > 2x + 9
y > (2/3)x + 3
Draw the line y=(2/3)x+3.
the y-intercept is (0,3) and the x-intercept is (-4.5,0).
Sub (0,0) into the inequality:
0 > 3 => NOT TRUE
Shade this unwanted region which is below the line.

Solve for y means you need to get y by itself. Move -2x to the other side by adding it on the left and adding it on the right side so the equation will look like this:
3y>9+2x
Next, solve for y by dividing everything by 3, so the answer becomes:
y>3+2x/3
