Question

Find coordinates for the point equidistant from (-1,5), (8,2), and (6,-2).

Answer 1

Try writing the point you are looking for as (x,y) and set up the distance formula involving each of the points. Set the radicals equal to one another and try to solve. Think you can do that?

Answer 2

Another idea might be to think of the 3 points as lying on the circumference of a circle whose centre you want to find.
