Step-by-step 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:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{80 - 40}{8 - 0}$

$m = \frac{40}{8}$

$m = 5$

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