Answer:
d - 7
Step-by-step explanation:
The word "difference" tells us that we will be using subtraction. Also, subtraction is not the same if you reverse the terms like, x - 2 and 2 - x are not the same. In your question it say "d and 7" so that's the order we use in the algebraic expression.
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
