Rebecca is traveling from Atlanta to Fort Myers by car. She drives at a constant rate of 70 mph and the distance between the two cities is 575 miles. Which equation represents the distance, y, in miles remaining after driving x hours?

• y = 70x - 575

• y = -70x + 575

• y = 575x + 70

• y = - 575x - 70
