Question

1. Write the equation of the circle given the following information. *

Center (-8,-9) and a radius r= 10

Answer 1

(x+8)² + (y+9)² = 100

Explanation:

The equation for a circle on a graph is

(x - a)² + (y - b)² = r²

r represents the radius

a represents the x displacement of the circle's center.

b represents the y displacement of the circle's center.
