An engineer records the number of centimeters the water levels rise in two reservoirs during a controlled closing of a dam. After 2 hours, the water level in Reservoir A increases by 8 centimeters. The water level change in Reservoir B is represented by the equation y = 8x, where y represents the water level in centimeters and x represents hours. Both reservoirs rise at a constant rate. Which statement correctly compares the rise of water in both reservoirs?
