Answer:
The average rate of change is 1
Step-by-step explanation:
The average rate of change can be expressed as the change in y over the change in x, then we can use the following formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Therefore, for the given points: (-0.5,2.5) and (0,3)
[tex]\begin{gathered} m=\frac{3-2.5}{0-(-0.5)} \\ m=\frac{0.5}{0.5} \\ m=1 \end{gathered}[/tex]
