For this case, the first thing you should know is that the point (8,28) is an ordered pair or equivalently a point P (x, y).
 This point represents the following rate:
 28/8 = 3.5 cm / min.
 Equivalently, it means that Olivia filled after 8 minutes, 28 centimeters of water. He did it at a speed of 3.5 cm / min.
 answer
 Time = 8 minutes
 Water level = 28 centimeters
 Speed = 3.5 cm / min
