Haven't brushed up on my algebra very much.
OpenStudy (anonymous):
-1/2 is not perpendicular to anything. But, a line with slope -1/2 is perpendicular to another line with slope 2.
OpenStudy (anonymous):
m1*m2=-1 if the two lines are perpendicular
OpenStudy (anonymous):
I'm talking about -2 and -1/2
OpenStudy (anonymous):
I know you are. I gave you the ones that are perpendicular. Your pair is therefore not.
