Step-by-step explanation
We want to find the rate of change of the graph given.
To do this, we apply the formula:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
where (x1, y1) and (x2, y2) are two points on the line.
From the given graph, let us pick the points (-1, -3) and (3, -5).
Therefore, the rate of change of the graph is:
![\begin{gathered} m=(-5-(-3))/(3-(-1))=(-5+3)/(3+1) \\ m=(-2)/(4) \\ m=-(1)/(2) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/so2513za1gu8jk3ydg5iuqrlnh49kfkvhu.png)
That is the rate of the change of the graph.
