15 Calculate the slope of the line passing through the given

15.) Calculate the slope of the line passing through the given points. Then indicate whether the line rises, falls, is horizontal, or is vertical.

(5,3) and (5,-2)

Solution

slope of line passing through points (a,b),(c,d) is m =(d-b)/(c-a)

slope of line passing through points (5,3) and (5,-2) is m =(-2-3)/(5-5)

m=-infinity

line is vertical
