The idea is this: the points that are a distance of 2 from the origin forms a circle with radius 2 around the origin. The equation for that circle around the origin is because the squares of the two sides formed by the x and y coordinates add up to the square of the hypotenuse.

In the given case, since the x and y are known to be equal, then you have
which means and . So,
Since the square root can be plus or minus, the only question remaining is which is it? The answer lies in the second quadrant, which means the x value is negative and the y value is positive. So the coordinates of a point with the absolute values of the x and y values being equal that lies 2 from the origin are ,
