Graph:
-9 ≤ -9x -27 < 9
What you have here is basically two equations, which you can solve one at a time or simultaneously:
-9 ≤ -9x -27 < 9 // add 27
18 ≤ -9x < 36 // div by -9, reversing inequalities because you div'd by a negative
-4 < x ≤ -2
Now graph both inequalities, x>-4 and x≤-2. Shade your solution ...
