Question 1015487
{{{(x-8)^2+(y+3)^2=4}}}
Center at (8, -3) radius=2
The point (8,-3) is not plotted: it is the center, not on the circle.
The radius is not plotted: it is the distance from center to the circle.
Four points will be: 
(6,-3)  (2 units (radius) left of center)
(10,-3) (2 units (radius) right of center)
(8,-5) (2 units (radius) below center)
(8,-1) (2 units (radius) above center) 
The circle goes through these four points.
The circle is all points 2 units away from the center.
