Answer
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.
Work Step by Step
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.
