What is the center of the circle..
in (x+2)2+(y+5)2=92?
(-2,-5)
in (y-3)2+(x-1)2=9?
3
if the center is at the origin with radius 2?
x2+y2=4
in (x-3)2+(y+4)2=252?
(3,-4)
in (y-5)2+(x-14)2 =42?
4
if the center is (5,-4) and the radius is 9?
(x-5)2+(y+4)2=81
in x2+y2=9?
(0,0)
in x2+(y-5)2 =289?
if the center is (0,-3) and the radius is √11?
x2+(y+3)2=11
if it has a diameter with endpoints (1,-3) and (2,1)?
(3/2, -1)
in (x+7)2+(y +5)2 =8?
2 √2
if the center is (-2,3), tangent to the x-axis
(x+2)2+(y-3)2=9
if it has a diameter with endpoints (-2,-3) and (8,-1)?
(3,-2)
in x2+(y − 3)2= 14?
√14
if the center is (-4,-2), tangent to the y-axis
(x+4)2+(y+2)2= 16
