Monica gets on an elevator in a skyscraper. The elevator starts to move at a rate of −20 ft/s. After 6 seconds on the elevator, Monica is 350 feet from the ground floor of the building. Select all that apply.

• x represents the time in seconds since Monica got on the elevator.

• The y-intercept represents the original height above the ground in feet.

• The elevator is moving up.

• The equation is y = 470 - 20x
