Answer:
As the slope is -2, so the rate of change of the function is:
Step-by-step explanation:
The slope is basically the rate of change of a function.
Let us take the two points from the graph
Taking the slope between two points to determine the rate of change of a function
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]
[tex]m=-2[/tex]
As the slope is -2, so the rate of change of the function is:
