Plot the circle from Question 2 by entering the standard form of the equation in the Input window. (Use ^2 to represent an exponent of 2.) Then plot the same circle using the general form of the equation that was given in Question 1. (Placing your cursor over an equation in the Algebra margin will bold the circle that the equation corresponds to. By right clicking and selecting Equation, you can toggle between the different forms of the equation.) Next, drag the equations of the circles onto the screen from the Algebra margin. Verify that the circles resulting from the two equations are the same.
