The following equation gives the amount of fuel left in a car, f(m), in gallons, as a function of the number of miles that have been driven, m, since the tank was full.
f(m) = 35 - 2.2m

If 0.2 is added to the slope of the equation to arrive at a new equation for calculating the remaining fuel, then which of the following is true?
