Unchangeable line.
Yay, first post! 
An analytic geometry problem.
Show that there are points that have the same coordinates at two cartesian coordinate systems with the same start O. Then, show that these points form a line in which O begins to, and finally try to describe it geometrically. Basically, the problem is to show that if you perform a turn on one cartesian coordinates system, there will still be some points left "untouched".
I find it interesting as a problem. Hope someone can help:)
