I. Identify the standard form of the following circles.

1. Center; (2,-1) r=4
2. Endpoints of the diameter (2,-1) and (6,3)
3. The center of the circle is (-3,2) passes through (8,0)
4. The circle passes through (2, -1), (3,1) and (-1,0)
5. The circle is tangent to the line x - y and has a center of (0,-2)

II. Identify if the graph exist on the following equation.

1. x² + y² – 6y - 100 = 0
2. x² + y² + 2x + y + 10 = 0
3. x² + y² – 3x – 2y + 10 = 0
4. x² + y² – 2x – 2y + 4 = 0
5 x² + y² + 2 = 0

III. Identify the equation of the circle in standard and general form.

1. Center; (2,-2) r= 1/2
2. The endpoints of the diameter are (1,3) and (-1,3)
3. The circle is concentric with x² + y² – 2x + 6y + 5 = 0 and passes through (3,-5)
