# Math Help - vector equation of intersection of line and plane

1. ## vector equation of intersection of line and plane

I have a plane that's given by the cartesian equation: $2x - 3y + 3z = 11$

I had to write down the equation of a line passing through point $P (1,2,-1)$ and perpendicular to the plane.

so I worked it to be: $(1,2,-1) + t(2,-3,3)$

Now I have to find the point at which the line intersects the plane. I know this is going to be very simple but I simply cannot see how to do it..

After I have that I have to find the shortest distance from the point to the plane, which I should be able to do by just finding the distance between the two points considering the shortest distance is perpendicular to the plane.

Any help is greatly appreciated.
