Answer:
The independent variable, x, represents the number of hours driven, and the dependent variable is the gallons of gas remaining, because the gallons of gas remaining depends on the number of hours driven.
A function relating these variables is K(x) =K(x)= 12-1.75x .
So K(4) = 5, meaning 4 hours of driving will result in 5 gallons left in the tank.
