Find the coordinates

Question

If the x -axis is the perpendicular bisector of a segment with an endpoint (2, 3), what are the coordinates of the other endpoint of this segment

Answer 1

(2,-3) are the needed co-ordinates.

Answer 2

Let (a, b) coordinates of second endpoints. Then (b + 3)/2 = 0 and b = - 3; but a can be any number,

So, second enpoint is any point on line y = - 3
