Késhaun conducted an experiment using a toy car and ramps of various heights. He measured the distance, y, in centimeters (cm), the toy car traveled from the end of the ramp. He also recorded the height, x, in centimeters (cm), of the ramp.

He found that when the ramp height was 18 cm, the toy car traveled 72 cm. When the ramp height was 27 cm, the toy car traveled 109 cm.

Which equation models this situation?
