An elevator descends at a constant rate of speed from the top floor to the first floor of an office building.
The equation below represents y, the height in feet of the elevator after x seconds. y=-5x +250
a. What is the y-intercept of the line represented by the equation?
b. What does the y-intercept represent in relation to the elevator?
c. What is the x-intercept of the line represented by the equation?
d. What does the x-intercept represent in relation to the elevator?
A second elevator in the same office building travels from the top floor to the first floor at a rate twice that of the first elevator.
e. Write an equation that can be used to represent y, the height in feet of the second elevator after x seconds.
