is it -8/0?

isnt that undefined?

Answer 1

Yes.

Answer 2

It is undefined but the numerator is not -8.

Answer 3

so i know it'd be a vertical line.

Answer 4

\[m=\frac{2+2}{4+(-4)}\]
\[m=\frac{4}{0}\]

Answer 5

Yes it is a vertical line but where...?

Answer 6

\[m=\frac{y-y1}{x-x1}\]

Answer 7

um. i thought slope was

y2-y1/x2-x1

Answer 8

Yes

Answer 9

so it would be 0/8 with is 0
