The graph shows the distance, in feet, required for a car to come to a full stop if the brake is fully applied and the car was initially traveling x miles per hour.

Question

A graph shows speed (miles per hour) labeled 10 to 100 on the horizontal axis and stopping distance (feet) on the vertical axis. A line increases from 0 to 60.

Which equation can be used to determine the stopping distance in feet, y, for a car that is traveling x miles per hour?

y =
y =
y =
y =

Answer 1

y = 1.5x
