Question

find the equation of set points which are equidistant from the point (1,2,3,) and (3,2,-1).​

Answer 1

Let A(1,2,3) and B(3,2,-1) are the given points and P(x,y,z) is the point that is equidistant from these two points.

⇒ 4x = 8z ⇒ x -2z = 0, which is the required equation.

Hope this helps!
