We are asked to find the image of (2,6), after a reflection in the line y=x
A reflection over the line y = x means to reverse the order of the (x, y) coordinates.
The rule for such a transformation is given by

Let us apply the above transformation to the given point

As you can see, we simply reverse the order of the coordinates.
Therefore, the image of the point (2, 6) after a reflection over the line y = x is (6, 2)
