A circle centered at (0,-8) passes through the point (2,5). Find the equation of the circle. Write your equation in the form (x - h)^2 + (y- k)^2 = r^2.

Center , h, k    =   (0,-8)

 

(x-0)^2 + (y+8)^2  = r^2       radus is distance from center to the other point given   use distance formula

 

d^2 =r^2=  2^2 +13^2  = 173

 

x^2 + (y+8)^2 = 173
