Question

Which of the following describes the graph of the solution for 13r<=-156?

Answer 1

13r <= -156 -- divide both sides by 13
r <= -156/13
r <= -12

If you are talking about a number line graph :
If there is an equal sign, then it is a closed circle.
(<) less then means shading to the left.

so it will be closed circle on -12 and shading to the left.

thanks
