Question

On a coordinate plane, a circle has a center at (1, negative 2) and a radius of 4 units.

Which equation represents a circle with the same radius as the circle shown but with a center at (-1, 1)?

Answer 1

(x + 1)^2 + (y - 1)^2 =16.

Explanation:

That would be

(x + 1)^2 + (y - 1)^2 = 4^2

---> (x + 1)^2 + (y - 1)^2 =16.
