Answer:
(x + 1)² + (y - 2)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 1, 2) and r = 3, thus
(x - (- 1))² + (y - 2)² = 3², that is
(x + 1)² + (y - 2)² = 9 ← equation of circle
