The set of points (x,y) such that the distance from (x,y) to (7,0) is equal to the distance from (x,y) to (-7,y). Use the Distance Formula to represent the description and simplify that equation.

The starting equation is
sqrt%28%28x-7%29%5E2%2B%28y-0%29%5E2%29=sqrt%28%28x-%28-7%29%29%5E2%2B%28y-y%29%5E2%29
