The relationship between the miles travelled and the gallons of fuel used is represented by
, whose graph is included below.
The performance of the particular car is described by a linear function, whose characteristics are shown below:
(1)
Where:
- Slope, in miles per gallon.
- Fuel capacity, in gallons.
- Travelled distance, in miles.
- Initial position, in miles.
If we know that
and
, then the linear function of the particular car is:
(2)
By the help of a graphing tool we have the expected graph for the particular car.
The relationship between the miles travelled and the gallons of fuel used is represented by
