Question

Let M and N be two points given be their coordinates in a Cartesian rectangular
coordinate system: M(1, 0, -2); N(5, -3, 6). Find the coordinates of such a point
C that divides the segment MN in a ratio 2:3 counting from M. Is it important for
the solution that the coordinate system is rectangular?

2:3   is  1: 3/2

maybe, find the length of MN and divide it by 3/2 would be a start
