Thread: Help on Vectors/Planes

Theres a question in my mathbook that first asks you to prove that two vector lines are parallel and then asks to find an equation of the plane determined by these two lines? Is it possibly for to parallel lines to form a plane?

If so, how do I go about doing it

Any two parallel (note that two means two distinct) always determine a plane.
You know that any there non-collinear points determine a plane.
So select two points from line and a point on the other line.
Then write the plane they determine.
