a) (x - 2)² + (y + 3)² = 9
b) (x + 2)² + (y - 3)² = 9
c) (x - 2)² - (y + 3)² = 9
d) (x - 2)² + (y + 3)² = 9

Answer 1

The equation of the circle is (x - 2)² + (y + 3)² = 9.

Step-by-step explanation:

The equation of a circle with center (2,-3) and radius 3 can be written as (x - 2)² + (y + 3)² = 9.
