The graph below shows the heights and arm spans of several basketball players at a tournament. Height and Arm Span of Students A graph has height (centimeters) on the x-axis and arm span (centimeters) on the y-axis. A trend line has a positive slope. The line goes through points (160, 160) and (170, 170). Based on the graph, which is the best prediction of the arm span of a player that is 202 cm tall? 195 cm 202 cm 210 cm 352 cm
