Question

(8,1);(8,-6) find the slope.

Answer 1

undefined

Explanation:

The formula for a slope is m=
`(y_(2)-y_(1) )/(x_(2)-x_(1))`

Let's say (8,1) represents
`x_(1)` and
`y_(1)`,

and (8,-6) represents
`x_(2)` and
`y_(2)`

m=
`((-6)-1)/(8-8)`

m=
`(-7)/(0)`

A number can't be divided by 0, so the answer would be undefined.

m= undefined
