Step-by-step explanation:

The center of a circle has two coordinates x and y. The x-coordinate is nest to the x and the y coordinate next to the y. But we change their signs.

(x - 13)  the x-coordinate is 13

(y - 1)    the y-coordinate is 1

Center = (13, 1)

The radius of a circle is in the right part of the equation but we need to get the square root of this number.

r² = 4; r = 2
