Determine which conic section is being described. (parabola, circle, ellipse or hyperbola)

1. x^2/9 + y^2/100 =1
2. y^2/25 - x^2/1 =1
3. x^2/28 - y =0
4. y^2/16 + x^2/16 =1
5. x^2 - (y-8)^2/26 =1
6. 1/80y^2 =x
7. (y+2)^2/49 + x^2/4 =1
8. 8.(x – 2)^2 + (y + 3)^2 =16
9. x^2 – 10x + 25 = y
10. (x-11)^2/144 - (y-1)^2/81 =1
Please help i need this to finish my virtual school class! Thanks (:
