On what point must the origin be shifted, if the coordinates of a point (4,5) become (ā3,9) ?
If the origin is shifted to the point (2, 3), the coordinates of a point become (5, -4). Find the original coordinates, when the axes are parallel.
New coordinates of the point (7,-1) would be, if the origin is shifted to the point (1,2) by translation of the axis.
