Equations of Circles - 500
Name the coordinates of a point on the circle
with equation (x 1)2 y2 4
Answer The center of the circle is (1, 0) and
the radius is 2. The easiest way to find the
coordinates of a point on the circle would be to
move 2 units above (1, 2), below (1, -2),
left (-1, 0), or right (3, 0) of the center.
