Question

find the perpendicular line of 3q-2p=-8;(1,2)

Answer 1

first, find the slope of the existing line:
1) -2p=-8-3q
p=3/2 q +4
so, the slope m =3/2

Answer 2

perpendicular line has the slope m1=-1/m
or m1=-2/3

Answer 3

3) now write the equation of perpendicular line @ point (1,2):
y-2=-2/3 (x-1)
y=-2/3 x +2/3 +2
y=-2/3 x +8/3

Answer 4

thanks so very much
