9. A tap is leaking into a pail. The height of the water in the pail is represented by the equation h = 0.5t + 2, where h represents the height of water in the pail, in cm, and t represents the amount of time the tap has been leaking, in minutes. What is the height of water in the pail if the tap has been leaking for 56 minutes? (Hint: y=mx+b)
