What is the center,given the equation
center is (3, 1), the radius of the circle is 3
(y-3)2+(x-1)2 =9
center is (5,-3) , the radius of the circle is 4
(y-5)2+(x+3)2 =16
center is (1,5), the radius of the circle is 5
(y-1)2+(x-5)2 =25
center is (-7,-5), radius of the circle is 7
(x+7)2+(x +5)2 =49
center is (3,0), the radius of the circle is 5
(x-3)2+y2 = 25
