Graph of a Circle

Write the equation of the circle.

• (x+1)² + (y +1)² = 3

• (x+1)² + (y -1)² = 3

• (x+1)² + (y +1)² = 9

• (x-1)² + (y -1)² = 9

In the equation
(x-3)²+(y-2)²=16, the center of the circle is...

• (3,2)

• (-3, -2)

• (-2, -3)

• (2, 3)

What are the coordinates of the center and the radius of the circle with equation:
(x - 4)² + (y - 3)² = 25 ?

• Center (4,3)
  Radius = 5 units

• Center (4,3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 25 units

• Center (-4,-3)
  Radius = 5 units

Select the matching graph.

Center is at (-3, 1) and radius is 3.

• (x + 3)² + (y - 1)² = 9

• (x - 3)² + (y + 1)² = 9

• (x - 3)² + (y + 1)² = 3

• (x + 3)² + (y - 1)² = 3
