Question

What does it mean when the slope is undefined??​

Answer 1

When the slope is undefined, it means that all points on the line have the same x-coordinate which means its an vertical line.

ex/.

If the 2 coordinates to find slope are (9,8) and (9,7)

the slope is undefined because

`(7-8)/(9-9)`=

-1/0

you can't divide by 0

So the slope is undefined

Answer 2

Explanation:

it means "an infinitely large slope" The x-coordinate never changes no matter what the y-coordinate is.
