Explanation:

Given

The attached graph

Required

Explain what the slope represents (Missing part of the question:)

First, we'll check the slope of the graph.

Represent time in weeks with x and savings in dollar with y

So, we have the following details:

`(x_1,y_1) = (0,40)`

`(x_2,y_2) = (8,80)`

Slope (m) is then calculated as thus:

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

`m = (80 - 40)/(8 - 0)`

`m = (40)/(8)`

`m = 5`

The calculated slope is positive and this implies that: As the number of week increases, the Andre's savings also increases
