Answer:
It is the third graph.
Explanation:
The first step is to subtract 12 from both sides, which gives you -8x ≤ -32. The second and final step is to divide by -8. Remember, when dividing by a negative the sign flips, so after you divide you have x ≥ 4. The ≥ sign means that x has to be greater than or equal to 4, so it is going to the right.
Hope this helps!
