You must get all answers correct before getting credit. Indicate whether the following equations define a straight line (L), a circle (C), an ellipse (but not a circle) (E), a parabola (P), or a hyperbola (H).
1. $(x-3)^2+(y+4)^2=9$
2. $(x-1)^2-(y+1)^2=1$
3. $2x-y+13=0$
4. $\frac{x^2}{9}+\frac{y^2}{2}=1$
5. $y = 5(x+11)^2 - 4$

Hint: All of these equations are in standard form.
