Question

The endpoints of the diameter of a circle are (-7, 3) and (5, 1). what is the center of the circle? (-6, 2) (-2, 4) (-1, 2)

Answer 1

The center of the circle is the midpoint of the endpoints of the diameter.
Center = ((-7 + 5)/2, (3 + 1)/2) = (-2/2, 4/2) = (-1, 2)

Answer 2

(-1, 2), because I said so.
