Hi

I'm not to sure how to approach this could someone help me out?

2 parallel lines:

L1=(1,0,0) + s(1,-1,-4)

L2=(2,4,0) + t(1,-1,-4)

Find a vector parametric equation of the plane the contains both these parallel lines.

edit: I'm thinking get another direction vector from (2,4,0)-(1,0,0)..is this correct?
