Answer:

(x - 4)² + (y + 3)² = 1

Explanation:

The equation of a circle is;

(x - a)² + (y - b)² = r²

Now, plug in the values of the center of the circle and the radius into the equation.

'a' will be the x value of the center, 'b' will be the y value of the center.

a = 4

b = -3

r = 1

(x - 4)² + (y - -3)² = 1²

(x - 4)² + (y + 3)² = 1
