Question 17548: Find slope given the following points: (2.5) and (2.1)

The slope of a line may be found by using the formula:
m=(y1-y2)/(x1-x2) where m is the slope of a line.
Let (x1,y1) = (2.5) and
Let (x2,y2) = (2,1)
so that
m = (5-1)/(2-2)
This is 4/0 which is undefined. When the denominator of a slope is undefined then this is a vertical line where one point is directly above the other.
