(x+3)² = 4(y+5)
What is the equation of the directrix?

• x = 4

• x = 2

• y = -4

• y = -6

What are the vertices of the hyperbola?

• (0, 3) and (0, -3)

• (-4, 3) and (-4, -3)

• (0, 1) and (0, -1)

• (4, 0) and (-4, 0)

Determine the equation of the hyperbola.

Write the standard form of the circle by completing the square: x² + y² +10y = 39

• x² + (y+5)² = 49

• x² + (y+5)² = 64

• (x+5)² + y² = 61

• (x+5)² + y² = 100

What is the equation used to find the focal points on an ELLIPSE?

• c² = a² + b²

• c² = a² - b²

• 1/4d

• (x-h)² + (y-k)² = r²

• hyperbola centre (2, -3).

• circle centre (2, -3), radius 2.

• ellipse centre (-2, 3).

• parabola vertex (2, -3)

• (-3, -3) and (7, -3)

• (1, -3) and (3, -3)

• circle centre (2, -3) and radius 1.

• ellipse centre (2, -3).

• hyperbola centre (2, -3).

• parabola vertex (2, -3).

Find the equation of the figure shown.

• (x-1)²/16 - (y+2)²/4 = 1

• (x+1)²/16 - (y-2)²/4 = 1

• (y+2)²/4 - (x-1)²/16 = 1

• (x-1)²/4 - (y+2)²/2 = 1
