Reflection of Circle

[luke]

Question: The equation of a circle with centre (0,5) and radius of length 2 units.
The circle is reflected along the line y=x.


I already found the equation of the circle which is x²+(y-5)²= 2² and the radius of the reflection circle which will be 2. But, I don't really know how to find the coordinates for the reflection circle. Can someone please help?

Draw the original circle (or at least its center point). Draw the reflection line. Do the actual reflection. What new center-point do you get? Proceed from there.
