49. In the standard(x, y) coordinate plane there is only one circle centered at the point (-1, 4) that also passes through the point (7, -2) Which of the following is an equation for that circle?

Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

Because the coordinates of the center of the circle are (-1, 4), C, D and E are excluded. And because (7, -2) is on the circle, the length of the radius is 10, so the value on the right side of the equal sign is 100. Choose B.
