how is it d? i need to know how to solve itt.

given perp....so u got the slope....assume it is of the form y=mx+c,m=4/3 nd it shud pass through (3,2)

OpenStudy (anonymous):

i'm still lost... lol can you draw it?

OpenStudy (anonymous):

actually i cant......:P see wen two lines are perpendicular.....product of their slopes is -1.......nd slope of ax+by+c=0 is -a/b.......
