a) The center-radius form of the circle equation is $(x - 5)^2$ + $(y + 4)^2$ = $49$ b) Refer to Graph I for the graphing.
Center of the circle = (5, -4) and Radius r = 7 a) The center-radius form of the circle equation is $(x – 5)^2$ + $(y – (-4))^2$ = $7^2$ $(x - 5)^2$ + $(y + 4)^2$ = $49$ b) Refer to Graph I for the graphing.
