Consider the line y = -4/3x - 3.
Find the equation of the line that is perpendicular to this line and passes through the point (8, -2).

y= -4/3x-3
(8,-2)
.......................
Since the given slope is -4/3, the slope you want is 3/4
Equation form is y=mx+b
Substitute to solve for b
-2 = 3/4(8)+b
-2 = 6+b
-8=b
Y= 3/4(8)+(-8)
................................
parallel?
slope is still -4/3
