Answer:
The average rate of change is -3
Step-by-step explanation:
we have
[tex]f(x)=-3x+1[/tex]
This is a linear function in slope intercept form [tex]f(x)=mx+b[/tex]
where
m is the slope
b is the y-intercept
In this problem
The slope is equal to
[tex]m=-3[/tex]
Remember that
In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval
therefore
The average rate of change is -3
