Acircle has a diameter with endpoints of (2, -8) and (6, 4). what is the center of the circle? (8, -4) (4, -2) (4, 6) (-3, 5)

The center to circle would be the middle of the diameter. To find this, add the x values and the y values to get something like this: the x values are 2+6=8 and y values -8+4=-4. Then you will divide both of your answers by 2, so it would be 8/2 for the x-coordinate and -4/2 for the y-coordinate. This will give you (4,-2).
