If the equation of a circle is (x - 2)2 + (y - 6)2 = 4, it passes through point ______.(2, 8)(5, 6)(-5, 6)(2, -8)

what you need to do is to plug the x and y value into the equation to see which one works.
(2-2)²+(8-6)²=0+4=4
so (2,8) is the answer.
Make sure by plugging in the other three pairs of values. You'll see that only (2,8) works.
