Introduction to Equations of Circles

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

• (3,2)

• (-3, -2)

• (-2, -3)

• (2, 3)

Which graph corresponds to 
(x)²+ (y-6)²=9

• A

• B

• C

• D

What is the equation of a circle with radius 2 and center (3, 4)?

• (x+3)² + (y+4)² = 2

• (x-3)² + (y-4)² = 2

• (x+3)² + (y+4)² = 4

• (x-3)² + (y-4)² = 4

What is the equation for this circle?

• (x+1)+(y+1)=9

• x²+y²=9

• x+y=9

• (x-1)²+(y-1)²=9
