OpenStudy (anonymous):

y = -3/4x + 2 3x - 4y = -8 would it be perpendicular?

OpenStudy (anonymous):

I think it's perpendicular, but my choices are perpendicular, parallel, or neither.

OpenStudy (the_fizicx99):

Its not parallel, I suck at drawing but it could be neither, for it to be perpendicular it would have to have a 90 degree angle.
