Given,
The coordinates of the points are (9, -9) and (2, 2).
Consider, P(x,y) is the point which is equal distance from the given points.
When the point is at equal distance from two given point then that point is called the mid point of the the line joining the given points.
The point is on the y -axis. So, the the coordinate of x-axis is 0.
The coodinates of P are,
Hence, the coordinates of the point equidistant from the given points is (0, -3.5) or (0, -7/2).
