Worksheet problem showing two circles, C1 and C2, with C1 centered at the origin and C2 touching the x and y axes, with the line y = x intersecting C1.

Two circles, C1 and C2, graphed on a coordinate plane. C1 is centered at the origin with radius 2. C2 is in the first quadrant, centered where the line y = x intersects C1, and touches both the x and y axes. The line y = x passes through both circles.
