I'm trying to find parametric equations for a line that passes through the point (0,1,2) and is perpendicular to the line:
x = 1 + t y = 1 - t z = 2t
Here's what I know: I have a directional vector, v, given by <1,-1,2> and another vector, r0, given by <1,1,0>. I can also make another vector for the point, P, <0,1,2>.
Can I use any of that information to solve my question? How?
