Point (x, y) is equidistant from (3, 6) and (-3, 4).
= \(\sqrt{(x-3)^2 + (y-6)^2}\)
= \(\sqrt{(x-(-3))^2 + (y-4)^2}\)
= \(\sqrt{(x-3)^2 + (y-6)^2}\)
= \(\sqrt{(x+3))^2 + (y-4)^2}\)
Squaring both sides, (x – 3)2+(y – 6)2 = (x + 3)2 +(y – 4)2
x2 + 9 – 6x + y2+ 36 – 12y = x2 + 9 + 6x + y2 +16 – 8y
36 – 16 = 6x + 6x + 12y – 8y
20 = 12x + 4y
3x + y = 5
3x + y – 5 = 0
