Question

A savings account balance can be misled by the graph of the linear function shown on the grid. What is the rate of change of the balance with respect to the number of deposits?

Answer 1

we have the following:

To answer the question we must calculate the slope as follows:

`m=(y_2-y_1)/(x_2-x_1)`

replacing:

`m=(450-50)/(4-0)=(400)/(4)=100`

therefore, the rate of change of balance with respect to tge number of deposits is equal a $100
