General Form of a Circle Rewrite the Standard Form of the equation of the circle below into General Form. (x + 3) 2 + ( y – 2) 2 = 16

General Form of a Circle Write the general form of the equation of the circle whose radius is 3 and center is located at (-3, 4).

General Form of a Circle Write the general form of the equation of the circle whose center is located at (-2, 3) and contains the point (1, 4).

General Form of a Circle Write the general form of the equation of the circle with a diameter with endpoints (4, 3) and (0, 1).

General Form of a Circle Graph the equation x 2 + y 2 + 4x - 6y + 12 = 0 First, put the equation in standard form so that you can identify the center and radius. (x 2 + 4x ) + (y 2 – 6y ) = -12 Next complete the square in each expression in parentheses. Remember the number added on the left side of the equation must be added to the right. (x 2 + 4x ) + (y 2 – 6y ) = -12

General Form of a Circle Graph the equation x 2 + y 2 + 4x – 4y – 1 = 0.

General Form of a Circle Graph the equation x 2 + y 2 + x + y – ½ = 0
