Answer:


(x + 2)^2 + (y + 5)^2 = 1

Explanation:

Equation of a circle:

The equation of a circle with center
(x_0,y_0) and radius r is given by:


(x - x_0)^2 + (y - y_0)^2 = r^2

Center: (−2, −5); radius= 1

This means that
x_0 = -2, y_0 = -5, r = 1. So


(x - x_0)^2 + (y - y_0)^2 = r^2


(x - (-2))^2 + (y - (-5))^2 = 1^2


(x + 2)^2 + (y + 5)^2 = 1

This is the equation of the circle.
