Which of the following is perpendicular to y = 2/3x - 2?

a)y = -3/2x + 1 b)y = 3/2x + 2 c) y = 2/3x + 1/2 d) y = 3x + 2

You can find the slope of the perpendicular line can be found by flipping the known slope upside down and making it negative. So, to find the slope of the perpendicular line, flip  upside down () and make it negative (-). Now, find the line that has the slope -.

The line perpendicular to y = x - 2 is A) y = - + 1.

8(1+tan^2x)+4tan^2x-12=0.
8+12tan^2x-12=0
12tan^2x=4
tanx=1/sqrt(3)
x=atan(1/sqrt(3))
x=0.5236
