Question

A circle 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)

Answer 1

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).
