How can I get the intersection point between 2 lines which are represented by 4 vectors?

There is the node “Line/Plane intersection” and since I only need 2D intersection, I think I could just create a plane out of one of the lines, but there is not documentation about planes, and I really dont know how to create a plane.

I guess W is Width, but what is X,Y,Z? If its a rotation, where do I set the location? If its a location, where do I set the rotation? I would really appreciate any help Either how to do Line/Line intersection manually or how to use the Line/Plane intersection with just 2 lines…
