Answer:
As the odometer increases the value decreases.
Explanation:
A car with a higher odometer means that it has been put to work more than the others and with this the risk of failure or mechanical problems increases, so the value of the car will be lower than that of the same car, same model and year but with less mileage. That´s why as the odometer increases the value of the car decreases, that would be the correlation.
