multiple choice

Every year, Luisa puts $10 into her savings account.

The barrel leaks 0.5 L of water each day.

Step-by-step explanation:

 A linear function has the form

The rate of change for a linear function always remain constant.

If every year, Luisa puts $10 into her savings account.

Here, the rate of change remains constant each year=$10

If the barrel leaks 0.5 L of water each day.

The rate of change in the quantity of water is constant  i.e. 0.05 L each day.

The rest of other situations do not have constant rate of change.
