r=2 center= (1,2) (x+1)^2 + (y2)^2 = 2 I was thinking I just take the radius and add it + or  on the Y axis from the center? Is there any analytical way to do this? I really don't like graphing! Thank a lot!

Given the circle: The points you desire are: In other words, the "highest" point is r units directly above the center and the "lowest point is r units directly below the center.
