Answer: graph B
Open hole at -9; shading to the right
=======================================================
Step-by-step explanation:
First we need to isolate x.
The inequality sign flips because we divided both sides by a negative number.
The graph of x > -9 will have an open hole at -9 and shading to the right.
This matches graph B
An open hole is used to tell the reader that the endpoint -9 is not part of the solution set. If we wanted to include it, then we'd have to involve "or equal to" as part of the inequality sign.
