Ellipse Quiz (5 Questions)

1. Identify a and b in (x² / 16) + (y² / 9) = 1

2. True or False: The sum of distances from any point on an ellipse to the foci is constant

3. Write the standard equation of an ellipse centered at (0,0) with a = 5, b = 3

4. Is this a horizontal or vertical ellipse: (x² / 4) + (y² / 9) = 1?

5. Find the center of (x − 2)² / 25 + (y + 1)² / 16 = 1

Answer Key

1. a = 4, b = 3

2. True

3. x² / 25 + y² / 9 = 1

4. Vertical (since b² > a²)

5. Center: (2, −1)
