Awatering 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?

{(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)}
