Question

Write the equation for the circle with center at (-8,-6) and radius of 10

(x•8)2 + (y + 5)2 - 10
(x+8)2 + (y + 6) 2 - 100
(4-8)2 + (y - 6)2 -100
d

Answer 1

The answer is (x+8)2 + (y+6)2-100

Answer 2

(x +8)² +(y +6)² = 100

Explanation:

The equation of a circle with center (h, k) and radius r can be written:

(x -h)² +(y -k)² = r²

For your given values of h=-8, k=-6, r=10, the equation is ...

(x +8)² +(y +6)² = 100
