Graph:
-9 &#8804; -9x -27 < 9

What you have here is basically two equations, which you can solve one at a time or simultaneously:
-9 &#8804; -9x -27 < 9 // add 27
18 &#8804; -9x < 36 // div by -9, reversing inequalities because you div'd by a negative
-4 < x &#8804; -2

Now graph both inequalities, x>-4 and x&#8804;-2. Shade ...
