We have that the slope of the line containing the pair of points f(1) = -6 and f(-7) = -6. is
[tex]m=\infty[/tex]
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
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore
[tex]m=\frac{-7-1}{-6-(-6)}\\\\ m= \infty[/tex]
Therefore
The slope of this line is
[tex]m=\infty[/tex]
