In the equation (x+2)²+(y-3)²=4, the radius of the circle is...

• 4

• 2

• 3

• 16

Which is the equation of the circle graphed below?

• (x - 3)² + (y + 4)² = 9

• (x - 3)² + (y + 4)² = 3

• (x)² + (y)² = 9

• (x - 1)² + (y + 1)² = 7

Write the equation of a circle with center (7, 0) with radius 3. 

• (x - 7)² + y² = 9

• x² + (y -7)² = 9

• (x - 7)² + y² = 3

• x² + (y -7)² = 3

Why are Conic Sections given this name?

• They are the cross-sections given when a cone is sliced.

• Because it's part of 'da rules'

• They are the cross-sections given when any 3D image is sliced.

• 3

• 6

• 2

• 4

What is the equation used to determine the focus points on an ELLIPSE?

• c² = a² + b²

• c² = a² - b²

• 1/4p

• (x-h)² + (y-k)² = r²

Is the major axis of the ellipse horizontal or vertical?

• horizontal

• vertical

• both

• neither
