Carlos is draining an aquarium. The graph shows the amount of water ( in liters) in the aquarium versus time ( in minutes
olya-2409 [2.1K]

Using a linear function, we have that:

a) The amount of water in the aquarium at 0 minutes is of 300 liters.

b) As time increases, the amount of water decreases at a rate of 60 liters per minute.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = ax + b

In which:

  • a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

In this problem, we have that the y-intercept is of 300, hence the amount of water in the aquarium at 0 minutes is of 300 liters.

The amount <u>decreases 60 liters in a minute,</u> hence:

As time increases, the amount of water decreases at a rate of 60 liters per minute.
