Question

Find the slope of the line passing through the pair of points:
(-6,-1), (-6,4)

Answer 1

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

We have the points (-6, -1) and (-6, 4).

Substitute:

`m=(4-(-1))/(-6-(-6))=(4+1)/(-6+6)=(5)/(6)\ !!!`

Dividing by 0 is not possible, therefore the slope is undefined.

It's a vertical line x = -6.
