The table below shows the result of an experiment that relates the height at which a ball is dropped, X , to the height of its first bounce, Y.

Drop height (x) (cm) Bounce height (Y) (cm)
100 26
90 23
80 21
70 18
60 16

Find x, the mean of drop heights, find y, the mean of bounce heights, find the linear regression that best fits the data. Write the equation you would use to show that (x,y) is a point on the line of regression
