Answer:
A. {(1, 6.7), (2, 6.4), (3, 6.1)}
Step-by-step explanation:
The watering can dispenses water at a rate of 0.3 gallon per minute and the original volume of water in the can was 7 gallons.
Let y represent the volume of water in the can in gallons
Let x represent time in minutes
f(x) = y = 7 – 0.3(x)
When x = 1,
y = 7 – 0.3(1)
= 7 – 0.3
= 6.7
The pair will be (1, 6.7)
When x = 2,
y = 7 – 0.3(2)
= 7 – 0.6
= 6.4
The pair will be (2, 6.4)
When x = 3,
y = 7 – 0.3(3)
= 7 – 0.9
= 6.1
The pair will be (3, 6.1)
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, 6.7), (2, 6.4), (3, 6.1)}
