If a point P(x, y) is equidistant from the points A(6, -1) and B(2, 3), find the relation between x and y.


Given: Point P(x, y) is equidistant from points A(6, -1) and B(2, 3)


i.e., distance of P from A = distance of P from B



Squaring both sides,


(x – 6)2 + (y – 1)2 = (x – 2)2 + (y – 3)2


x2 – 12x + 36 + y2 – 2y + 1 = x2 – 4x + 4 + y2 – 6y + 9


–12x + 36 + 2y + 1 = –4x + 4 – 6y + 9


–8x + 8y = –24


x – y = 3


Therefore, x – y = 3 is the required relation.
