An Example of Direct Variation. If y represents the miles traveled by a person driving down the highway at a speed of 50 MPH and x represents the hours spent traveling, then y = 50x and x and y vary directly. We also say that x is directly proportional to y. So if the person travels for x = 2 hours, they will cover y = 50(2) = 100 miles.
