The relationship between a professional basketball player's height h in inches and weight w in pounds was modeled using two samples of players. The resulting modeling equations for the two samples were w = 7.46h - 374 and w = 7.93h 405. Assume that 65 ≤ h ≤ 85. 

(a) Use each equation to predict the weight of a professional basketball player who is 6'11". 

(b) Determine graphically the height where the two models give the same weight. 

(c) For each model, what change in weight is associated with a 1-inch increase in height?
