Question

Which is an equation of a circle with center (-5, -7) that passes through the point (0, 0)?

(x - 5)2 + (y - 7)2 = 37
(x + 5)2 + (y + 7)2 = 74
(x - 5)2 + (y - 7)2 = 74
(x + 5)2 + (y + 7)2 = 37

I know this!

Answer 5

Ok so a circle has the equation

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

The (h, k) is the center, so check this... (-5, -7) has to have

(x+5)^2 + (y+7)^2
