The number of miles that can be driven is proportional to the number gallons of gas. The graph of the equation y = 31x shows this relationship.
Explain why the ordered pair (0, 0) is on this graph.
A. When the tank is full, 0 miles can be driven.
B. When 0 miles are driven, there is no gas used.
C. When there is no gas in the tank, 0 miles can be driven.
D. When the tank is full, the driver does not have to worry about how much gas is used?
