Question

Is -1/2 perpendicular to -2?

Answer 1

Haven't brushed up on my algebra very much.

Answer 2

-1/2 is not perpendicular to anything.

But, a line with slope -1/2 is perpendicular to another line with slope 2.

Answer 3

m1*m2=-1 if the two lines are perpendicular

Answer 4

I'm talking about -2 and -1/2

Answer 5

I know you are. I gave you the ones that are perpendicular. Your pair is therefore not.

Answer 6

Alright.
