Warmup Find the distance between the point (x, y) and the point (h, k).

Write equations of circles. Graph circles.

Circle: the set of all points in a plane that are equidistant from a given point in the plane, called the center. Any segment with endpoints at the center and a point on the circle is called a radius of the circle

Write an equation for the circle with given center and radius.

Write an equation for the graph.

Write an equation for the circle given the endpoints of a diameter.

Find the center and radius of the circle. Then graph.

Find the center and radius of the circle. Then graph.

Write an equation for the circle that satisfies this condition.
