Question 937318: When draining her hot tub, the height of the water in Brittany�s hot tub decreases at a rate of 2 inches per minute. After 9 minutes there are 11 inches of water in the tub. Assume that the height is decreasing at a constant rate. Write an equation for the height of water left in the tub (h) as a function of the number of the minutes (t) that have elapsed.

rate = -2/1 inches/minute
rate = -2 inches/minute

h - 11 = -2(t - 9)
h = -2t + 18 + 11
h = -2t + 29
