Answer:
-3.3125[tex]\frac{-10.125-(-3.5)}{4-2} =\frac{-6.625}{2} = -3.3125[/tex]
Step-by-step explanation:
Average rate of change is the slope between two points.
Slope getween points [tex]\left(x_1,\,y_1\right)[/tex] and [tex]\left(x_2,\,y_2\right)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
Using the points (2, -3.5) and (4, -10.125), the slope is
