Answer:
Number line D is true
Step-by-step explanation:
Given
See attachment for number lines
Required
Which number line makes the inequality true
First, we solve for x in
Divide through by -3
The inequality means x is greater than -2.
This means that, the line must point to the right of -2 and the "greater than" means that the circle must be opened
Number line D is true
