A bathtub was originally filled with 50 gallons of water. It DRAINS at an average rate of 5 gallons per minute. What is the rate of change (m) and initial value (b) of the linear equation that models the amount of water in the bathtub after it starts draining?

• The rate of change is 5 gallons per minute, and the initial value is 50 gallons.

• The rate of change is -5 gallons per minute, and the initial value is 50 gallons.

• The rate of change is -50 gallons per minute, and the initial value is 5 gallons.
