Answer:
A, the first option
Step-by-step explanation:
1. Add 15 to both sides to cancel out the 15 from the left. (5x < -50)
2. Divide both sides by 5 to cancel out the 5 from the left. ( x < -10)
This inequality does not include the -10 because it's <em>less than</em> -10 not less than or equal to. So, the point at -10 should not be filled in.
x has to be LESS than, so the graph should include numbers that are less than -10 which leads us to our answer, A.
