Question states "The Cartesian equation of the plane containing the line x=3t, y=1+t, z=2-t and passing through the point (-1,2,1) is?"
I know I need to get the vector normal from the parametric equations, but I don't know how to do this, and than apply the relationship
ie <n1,n2,n3> . <x-(-1), y-2, z-1 > = 0
So I think the biggest problem I have is trying to work out the vector normal from the parametric
