The graph shows
[tex] m \ge -60 [/tex]
Now we need to turn it into one of the choices.
Subtract m from both sides.
[tex] 0 \ge -60 - m [/tex]
Add 60 to both sides.
[tex] 60 \ge -m [/tex]
Now multiply both sides by -1. (Remember to change
the direction of the inequality sign.)
[tex] -60 \le m [/tex]
Answer: A.
