Homework Statement



Find the Vector eqn of a line which passes through P(2, -1, 3) and is perpendicular to the plane 3x -2y -z =0.

Homework Equations



Line(x) = P + td where d is a direction vector

The Attempt at a Solution



My main problem here is trying to find the direction vector for the line. I have really no idea how to find that. Any help is greatly appreciated :)

I think I figured it out...I can use the normal vector of the plane as my direction vector.
