Name ______________________________

1. Find the midpoint of the line segment joining A and B and the distance between A and B. (Memorize these

formulas).

a.) A: (–1, 4), B: (–2, –2)

b.) A: (2, –5), B: (4, 1)

Midpoint ____________ Distance ____________

2. Standard form of a circle: (x – h)

+ (y – k)

= r

. Write the standard form for a circle whose center is (2, –5) and

r = 3.

3. Complete the square to convert the general form of the circle to standard form. List the center and the radius.

a.) x

+ y

– 2x + 4y – 9 = 0

b.) x

+ y

– 4y = 0

Center: _________ Radius: _____________
