The ratio of the weight of an object on Mercury to its weight on Earth is 0.38.

a. Explain why you can use the equation m = 0.38e to model the weight of an object on Mercury.
b. How much would a 160-pound student weigh on Mercury?
c. The ratios for the Moon and Jupiter are 0.17 and 2.54 respectively. The equations y1 = 0.38x, y2 = 1x, y3 = 0.17x, and y4 = 2.54x are graphed at right. Match each planet with its graph and equation
