Help!!!!!!!!! Hi everyone, This is my very first post on physics forum! I was wondering if anyone could help explain to me how to find the coordinates of a point where a line intersects a plane. The question i'm trying to do has given the line as r= (2, 7, -5) + t(1, 2, -1) and the plane as 2x + 3y - z=3. Any advice or help would be much appreciated, thank you.
