The assignment is incorrectly written, we will rewrite it correctly.
(x – 5) ^ 2 + (y + 9) ^ 2 = 16;
The general equation of a circle is:
(x – x0) ^ 2 + (y – y0) ^ 2 = R ^ 2, where x0 and y0 are coordinates, r is the radius.
The coordinates will then be equal: x0 = 5, y0 = -9 or (5; -9). And the radius: r = 4.
Answer: (5; -9).
