1. The problem statement, all variables and given/known data Find the line through (3, 1, -2) that intersects and is perpendicular to the line x = -1 + t, y = -2 + t, z = -1 + t. 2. Relevant equations line l through P (x1, y1, z1) and Q (x2, y2, z2) has the following form x = x1 + (x2 - x1)t y = y1 + (y2 - y1)t z = z1 + (z2 - z1)t 3. The attempt at a solution Alright so I'm pretty sure that this is a REALLY easy problem, but I just started vector calculus and I keep mixing up my steps and my variables. first of all, I'm trying to solve what the point of intersection would be, and I was trying to use the equations above, but then I wasn't really sure what I was doing...can anyone help to point me in the right direction? thank you.
