A speed camera records the distance that a car travels along a straight road by taking snapshots of the traveling car at two different times. The first snapshot shows the car is 36 ft away from the speed camera. After half a second the second snapshot shows the car is 8 ft away from the speed camera. Assume that the car is traveling at a constant speed.

b. Find a linear equation that models the car's distance y traveled for any amount of time x .
c. How many seconds after the first snapshot does it take for the car to reach the speed camera?
d. How far away from the speed camera was the car 1.5 seconds before the first snapshot was taken?
