ANSWER
Step-by-step explanation
We want to find the rate of change of the graph given.
To do this, we apply the formula:
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:
That is the rate of the change of the graph.
