Identify the equation of the circle D with center D (-8,-1) and radius 3.

(x + 8) ² + (y + 1) ² = 9

Step-by-step explanation:

Equation of a circle

(x - h) ² + (y - k) ² = r²

(x - - 8) ² + (y - - 1) ² = 3²

(x + 8) ² + (y + 1) ² = 9

(h+8) ^2 + (y + 1) ^2 = 9

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 + (y-k) ^2 = r^2

where (h, k) is the center and r is the radius

(h - - 8) ^2 + (y - - 1) ^2 = 3^2

(h+8) ^2 + (y + 1) ^2 = 3^2

(h+8) ^2 + (y + 1) ^2 = 9
