Question: In Problem 1-8, name the conic (horizontal ellipse, vertical hyperbola, and so on) corresponding the given equation. 1. x2/9 + y2/4 = 1 2. x2/9

In Problem 1-8, name the conic (horizontal ellipse, vertical hyperbola, and so on) corresponding the given equation.
1. x2/9 + y2/4 = 1
2. x2/9 - y2/4 = 1
3. - x2/9 + y2/4 = 1
4. -x2/9 + y2/4 = -1
5. -x2/9 + y/4 = 0
6. -x2/9 = y/4
7. 9x2 + 4y2 = 9
8. x2 - 4y2 = 4
