Ineed to know how to get the answer

Step 1: Add 9 to both sides
Step 2: Combine like terms (notice the -9 and 9 cancel out)
Step 3: Flip the inequality

-16 > x - 9
-16 + 9 > x - 9 + 9 ... apply step 1
-7 > x ... apply step 2
x < -7 ... apply step 3

The final answer is x < -7
Any value smaller than -7 will work as a solution

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
