#### Answer

a) The center-radius form of the circle equation is
$(x - \sqrt{2})^2$ + $(y - \sqrt{2})^2$ = $2$
b) Refer to Graph I for the graphing.

#### Work Step by Step

Center of the circle = $(\sqrt{2}, \sqrt{2})$ and Radius r = $\sqrt{2}$
a) The center-radius form of the circle equation is
$(x – \sqrt{2})^2$ + $(y – \sqrt{2})^2$ = $(\sqrt{2})^2$
$(x - \sqrt{2})^2$ + $(y - \sqrt{2})^2$ = $2$
b) Refer to Graph I for the graphing.
