1
Convert the equation to standard form. 4x
2
+ 4y
2
- 4x +16y +1 = 0
(x - 0.5)2 + (y + 2)2 = 16
(x - 0.5)2+ (y + 2)2 = 4
(x + 0.5)2 + ( y - 2)2 = 4
(x - 1)2 + (y + 2)2 = 4.75

= 16. Find the center and the radius.
center (1, 5), radius 256
center (0, -5), radius 4
center (1, -5), radius 4
center (0, 5), radius 256

What point partitions the directed line segment KL into a ratio of 2 to 1 if K(−2,1) and L(4,7) ?
(0,−3)
(−1,−2)
(2,5)
(−3,−3)
5
Write the equation of the circle graphed.
(x + 2)2+ (y + 2)2 = 3
(x + 2)2 + (y + 2)2 = 9
(x - 2)2+ (y - 2)2= 9
(x - 2)2+ (y - 2)2 = 3

11
Write the equation of the circle graphed.
(x - 2)2 + (y + 1)2= 16
(x + 2)2 + (y - 1)2= 16
(x - 2)2 + (y + 1)2= 4
(x + 2)2 + (y - 1)2= 4
12
