(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The linelpasses through the point P=(1,-1,1) and has direction vector d=[2,3,-1]. Determine whether l and P are parallel, perpendicular, or neither to 2x+3y-z=1.

2. Relevant equations

n.x=n.p, also cross product for parallel lines, and dot product for perpendicular.

3. The attempt at a solution

I don't know how to relate the point, P, to the directional vector,d. I am pretty sure that I can do the rest.
