Question

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

A. -2
B. 0
C. undefined
D. 5/4

Answer 1

C. undefined

Step-by-step explanation:

The coordinates of the line is given as:

(4, -6) and (4, 4).

x1 = 4

y1 = -6

x2 = 4

y2 = 4

Slope =
`(y2 - y1)/(x2 - x1)`

Now insert the parameters and solve;

Slope =
`(4-(-6))/(4-4)` = undefined

The slope of the line is undefined
