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

Best ResponseYou've already chosen the best response.0You can use distance formula (without square root) to find \(r^2\): \[d^2 = (x_1x_2)^2+(y_1y_2)^2\]

Best ResponseYou've already chosen the best response.0So you would have this after plugging in: \[d^2 = (50)^2+(70)^2 = \cdots~?\]
