Answer:
The graph has a closed circle, the arrow points left and -7 is part of the solution.
Explanation:
Consider the provided inequality:

Add -x to both sides of the inequality.


Now add -15 to both the sides of the inequality.


Therefore,

This means x can be any real number which is less then or equal to -7. Thus, the arrow points to the left.
Use an closed circle for the sign

Therefore the correct answer is:
The graph has a closed circle, the arrow points left and -7 is part of the solution.
