Hi,

Find an equation of the circle that satisfies the given conditions.

Center (−4, 7); passes through (−9, −5)

(-4,7)

(-9,-5)  r = sqrt%28%28-4%2B9%29%5E2+%2B+%287%2B5%29%5E2%29+=+sqrt%28169%29 = 13

equation of the circle that satisfies the given conditions:

%28x%2B4%29%5E2+%2B+%28y-7%29%5E2+=+13%5E2
