eg to find the point 1/3 rd way from the start of line(A , B) one could calculate 2/3 *A +1/3 * B.

I think it is more natural to compute this as A + (1/3)*(B - A), where A and B are points and B - A is a vector. So you're really still just adding a vector to a point to get a new point. There is never a need to add or rescale points.
