Kevin gets on an elevator in a skyscraper. The elevator starts to move at a rate of -15ft/s. After 4 seconds on the elevator, Kevin is 260 ft from the ground floor of the building.
Write an equation in Slope Intercept Form (y=mx+b) for the motion of the elevator since it
started to move. Use the variables x and y in your equation.
