Which is the radius of the circle with equation

(x - 2)² + (y + 4)² = 9

• 81

• 3

• 9

• 4.5

What is 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

If the focus of a parabola is (0, –3) and its directrix is y = 3, then its equation is

• x² = –12y
• x² = 12y
• y²= 12 x
• y²= -12 x

What is the directrix of the parabola
(x - 4)² = 8(y + 3)?

• y = - 3
• x= 5
• y= - 5
• y= 2

6y² – 5x – 2y + 5 = 0

• Parabola
• Circle
• Hyperbola
• Ellipse

Find the equation of the figure shown.

• (x-5)² + (y-3)² = 25
• (x+5)²/4 + (y+3)²/9 = 1
• (x-5)²/2 + (y-3)²/3 = 1
• (x-5)²/4 + (y-3)²/9 = 1
