Explanation:
We are asked to get the slope of the graph
To do so, we have to make use of the relationship:
[tex]\text{slope}=\frac{\text{rise}}{\text{fall}}=\frac{\text{change in y}}{change\text{ in x}}[/tex]
From the graph given
We have the following points:
[tex](1,8)\text{ and (2,4)}[/tex]
So we can obtain the slope as follow
[tex]\text{slope}=\frac{4-8}{2-1}[/tex]
Thus, the slope
[tex]\text{slope}=\frac{-4}{1}[/tex]
