Answer:
The picture is too blurry to see, so let me explain how you find the answer for yourself...
Explanation:
Basically, time is the y-axis (up and down), and # of rebounds is the x-axis (left and right). The question asks for rebounds made in 15 minutes, so first find the 15 mark on the left of the graph. Trace that line across the graph to the right (use ur finger if you have to) until you hit a dot. Trace the line that the dot is on down to the bottom of the graph. The number you hit will be your answer (# of rebounds).
~Hope this helps :)
