Provide an appropriate response.Why is the slope of a horizontal line equal to zero? Give an example.
What will be an ideal response?
Answers may vary. One possibility: The slope of a horizontal line is equal to zero because the y-values do not change as the x-values change. For example, the points (3, 4) and (7, 4) are two points on a horizontal line. The slope of this line is zero because m = 
= 
= 0.
