Carlos is draining an aquarium. The graph shows the amount of water ( in liters) in the aquarium versus time ( in minutes

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.
A linear function is modeled by:
y = ax + b
In which:
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 decreases 60 liters in a minute, hence:
As time increases, the amount of water decreases at a rate of 60 liters per minute.
