Answer:
A
Step-by-step explanation:
In the inequality, you want to simplify it to get x on one side, and the numeric values on the other. 
So, moving 9 to the other side, you get, 8x<-32
Then, you can divide by 8 on both sides to get x alone. 
You get, x<-4. 
From this, we can see that it should be an open dot at -4, and pointing to the left. 
So, the correct number line is A.
