Question

A car starts a journey with a full tank of gas. The equation y=16 - 0.05x relates the number of gallons of gas, y, left in the tank to the number of miles the car has traveled, x.

A. What are the x- and y-intercepts of the graph of this equation?

B. What does x-intercept represent in the context of this problem?

C. What does y-intercept represent in the context of this problem?

Answer 1

A. The y-intercept is y = −0.05 x + 16 and the x-intercept is x = −20y + 320

B. The x-intercept represents the number of miles the car has traveled.

C. The y-intercept represents the number of gas in gallons.
