Answer:
The average slope is 8.
Step-by-step explanation:
Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient
average slope = 
To find the average slope of the function
on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.
So,

The average slope is
