Answer:
The rate of change is equal to 3
Step-by-step explanation:
we know that
The rate of change of the linear function (line) is the slope
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
take two points from the graph
(0,-4) and (2,2)
substitute the values
[tex]m=\frac{2+4}{2-0}[/tex]
[tex]m=\frac{6}{2}[/tex]
[tex]m=3}[/tex]
