Question

What is the slope of the line that passes through the points (-1, -10)(−1,−10) and (-1, -2) ?(−1,−2)? Write your answer in simplest form.

Answer 1

undefined

Explanation:

We can find the slope of the line using

m = (y2-y1)/(x2-x1)

= (-2 - -10)/(-1 - -1)

= (-2+10)/(-1+1)

= 8/0

When we have a 0 in the denominator the slope is undefined
