a) The center-radius form of the circle equation is $(x + 2)^2$ + $(y - 5)^2$ = $16$ b) Refer to Graph I for the graphing.

Center of the circle = (-2, 5) and Radius r = 4 a) The center-radius form of the circle equation is $(x – (-2))^2$ + $(y – 5)^2$ = $4^2$ $(x + 2)^2$ + $(y - 5)^2$ = $16$ b) Refer to Graph I for the graphing.
