Question

What is the slope of the line that passes through the points (0, 6) and (0, -5)?

Write your answer in simplest form.

Answer 1

Ok so slope is the change in y over change in x.
Your why changed from 6 to -5 so you can write this as -5 - 6
Your x didn’t change it went from 0 to 0
You can write this as 0-0
Now -11/0 is what you end up with as a slope.
Any number divided by 0 is undefined so your slope is undefined
