30 ! will mark you ! the graph below shows the heights and arm spans of several basketball players at a tournament. 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

Whenever you're asked to find the best prediction based on the graph, you always use the line of best fit (the black line) that is determined from your data points.

Since 202cm isn't on your graph, you will need to write an equation for your line of best fit and mathematically figure out the arm span. If you look at your graph, notice that for every x value, the y value is equal to it. That makes writing the equation easy. Since x=y, your equation is pretty much just y = x. 

Your x value that you need to plug in is x=202cm. This is because height is on the x axis and the height you want to find the arm span for is 202cm. Plug x=202 into the equation:
y=x
y=202

The arm span of a player that is 202 cm tall is B) 202cm wide.
