A watering can dispenses water at a rate of 0.35 gallon per minute. The original volume of water in the can was 9 gallons. Which set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water?

Answer: {(1, 8.65), (2, 8.30), (3, 7.95)}   EXPLANATION   Given, The watering can dispenses water at a rate of 0.35 gallon per minute. The original volume of water in the can was 9 gallons.   Therefore if, y = the volume of water in the can in gallons x = time in minutes f(x) = y = 9 – 0.35x   When x = 1, y = 9 – 0.35(1) y = 9 – 0.35 y = 8.65 Therefore we have the pair (1, 8.65)   When x = 2, y = 9 – 0.35(2) y = 9 – 0.7 y = 8.3 Therefore we have the pair (2, 8.30)   When x = 3, y = 9 – 0.35(3) y = 9 – 1.05 y = 7.95 Therefore we have the pair (3, 7.95)   The set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water is {(1, 8.65), (2, 8.30), (3, 7.95)}
