This video is a demonstration of problems involving Circles. In this practice problem you are asked to find the standard form of the equation of the circle and then sketch the graph of the circle. The point (2, 3) lies on the circle with its centre at (-1, 1). The equation given for the circle is (x - h)2 + (y - k)2 = r2Learning Design
Use General and Standard Equations of a Circle.
Convert one equation to the other by completing the square (gives Standard Equations) or expanding (gives General Equation).
