Question

Find the slope of the line that contains (4, -6) and (4, 4).

Answer 1

Answer:

C. undefined

Explanation:

 The coordinates of the line is given as:

                  (4, -6) and (4, 4).

x1   =  4

y1  = -6

x2  = 4

y2  = 4

  Slope  = $\frac{y2 - y1}{x2 - x1}$    

  Now insert the parameters and solve;

  Slope  = $\frac{4-(-6)}{4-4}$  = undefined

The slope of the line is undefined
