Determine whether the planes are perpindicular
(-2, 1, 4) . (x-1, y, z+3) = 0 (PLANE A)
(1, -2, 1) . (x+3, y-5, z) = 0 (PLANE B)
Here's what I have figured out so far:
Plane A passes through (1,0,-3) and is perpendicular to (-2,1,4)
Plane B passes through (-3, 5, 0) and is perpendicular to (1, -2, 1)
I know that if I had to determine if they were parallel, (1,0,-3) and (-2,1,4) would have to be along the lines of (-1, 2, 4) and (2, -4, -8).
I'm not sure if I'm on the right track and missing something right in front of me, or completely lost altogether.
