Simple vectors question

nobodythere · 2007-04-28 17:22:43

There is more to the answer but it's not relevant. Can someone explain to me why p and q would lie along L1 and L2? Taking L1 as an example I would have thought that 4i+2j-k would kind of 'offset' the vector so to speak so that p would not lie along it. ???

What is meant is...

the line L 1 is parallel to the direction of the vector p,

and line L 2 is parallel to the direction of the vector q.
