Answers

1
Consider the equation (x - 3)² + (y - 2)²= 25. Find the center and the radius.
center (3, 2), radius 25
center(-3, -2), radius 5
center (3, 2), radius 5
center (-3, -2), radius 25
2
If a line segment was drawn between the two points, the midpoint would be ___.
(-2, 4)
(-4, 2)
(-1, 4)
(0, 4)
3
Write the equation of the circle graphed.
(x - 1)2 + (y - 2)2 = 4
(x - 1)2 + (y -2)2 = 16
(x + 1)2 + (y + 2)2= 16
(x + 1)2+ (y + 2)2 = 4
4
Consider the equation, (x - 2)²+ (y + 5)² = 21. Find the center and the radius.
center (-2, 5) radius 21
center (2, -5) radius 21
center (2, -5) radius √21
center (2, 5) radius √21
5
Write the equation of the circle graphed.
(x + 2)2 + (y - 1)2= 16
(x - 2)2 + (y + 1)2= 4
(x + 2)2 + (y - 1)2= 4
(x - 2)2 + (y + 1)2= 16
6
Convert the equation to standard form: x²+ y² -4x +2y = 4
(x - 2)2 + (y + 1)2= 3
(x + 2)2 + (y + 1)2 = 9
(x -4)2 + (y + 2)2 = 4
(x - 2)2+ (y + 1)2 = 9
7
Consider the equation, x²+ (y + 5)² = 16. Find the center and the radius.
center (0, 5), radius 256
center (1, -5), radius 4
center (1, 5), radius 256
center (0, -5), radius 4
8
Convert the equation to standard form. x² + y² - 4x + 2y = 11
(x + 2)2 + ( y - 1)2 = 16
(x - 2)2 + (y + 1)2 = 11
(x + 2)2 + (y - 1)2 = 11
(x - 2)2+ (y + 1)2 = 16
9
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 = 3
(x + 2)2 + (y + 2)2 = 9
10
Convert the equation to standard form. x²+ y² -20x - 16y = -139
(x + 10)2 + (y + 8)2 = 25
(x - 10)2 + (y - 8)2= 5
(x - 10)2+(y - 8)2= 25
(x + 10)2 + (y + 8)2 = 5
