Consider the circle that is centered at the origin and contains the point
Use geometry and the definition of a circle, but not the algebraic equation for a circle, to prove or disprove that the point
lies on this circle.
Any line from the origin to the edge of the circle will be 3 units long.
Find the distance from the origin to
Find at least one value of x so that the point
lies on the circle. or
other points on this same circle.
Write the equation for this circle and find values of
and that satisfy the equation.
