4. In Jay's business, the annual cost of operating a car, C, is a linear function of the number of
kilometres the car is driven, k. The annual cost
of operating a car that has been driven 20575 km
is approximately $3775. The annual cost of
operating a car that has been driven 21 200 km
is approximately $3800. If points are
(20575, 3775) and (21200,3800), write an
equation in slope-point form to represent this
function.
