According to the table, what was the rate of change between March and April?
students per month

Answer 1

The rate of change between March and April is
`-11`

Step-by-step explanation:

The rate of change is defined by how one quantity changes in relation to another quantity.

For x is the independent variable and y is the dependent variable, where

x is the Month and y is the students.

The rate of change can be determined using the formula,

`rate of change=(y_(2)-y_(1))/(x_(2)-x_(1))`

Substituting the values, we get,

`rate of change=(63-74)/(4-3)`

Simplifying, we get,

`rate of change=(-11)/(1)`

Dividing,

`rate of change=-11`

Thus, the rate of change between March and April is
`-11`
