Step-by-step explanation:

We have that the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6. is

From the question we are told
Find the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6.
Where Standard form of Equation is
y=mx+c
Generally the equation for the Slope is mathematically given as

Therefore

Therefore
The slope of this line is
