Ryan’s teacher asked him to graph circle E with equation (x – 5)2 + y2 = 25. Below is the graph he submitted.
Circle E that contains points 30, 0; 5, negative 25; negative 20, 0; 5, 25.
What, if anything, did Ryan do wrong when graphing this equation?

His circle satisfies
(x5)^2 + y^2 = 25^2
not just 25.
