OG12 Geometry

by GMATMadeEasy » Wed Apr 20, 2011 2:09 pm
In the rectangular coordinate system above, the line y = x is the perpendicular bisector of segment AB (not shown), and the x-axis is the perpendicular bisector of segment Be (not shown). If the coordinates of point A are (2,3), what are the coordinates of point e ?

(A) (-3,-2)
(8) (-3,2)
(e) (2,-3)
(D) (3,-2)
(E) (2,3)

Could some one solve it please without using OG method (that is property of reflection of a point) . I want to see the methods to be used to compute the point B.
