Question

9. Write an equation of a circle with the given center and radius.

center (-7,-6) and radius 2
0 (x-7)2 + 0 -6- =
(x – 7)2-6-6)2 =
- 7)-- *
fax - 7)--
is

Answer 1

(x +7)^2 +(y +6)^2 = 4

Explanation:

The equation for a circle with center (h, k) and radius r is ...

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

Filling in the values (h, k) = (-7, -6) and r = 2, we have ...

(x +7)^2 +(y +6)^2 = 4
