anonymous · Answer

$$\frac{ x ^{2} }{ 9 } + \frac{ y ^{2} }{ 100 }$$

anonymous · Answer

^ that one = 1

anonymous · Answer

y^2/25 - x^2/1 = 1
x^2/28 - y = 0
y^2/16 + x^2/16 = 1

anonymous · Answer

Can you just help me with these for now and I'll ask for help on others if I can't figure them out later?

A positive x^2 and positive y^2 means either an ellipse or circle. If the number in the denominators is the same, then circle.

An x^2 and y^2 with one negative means hyperbola.

An x^2 OR y^2 but not both, means parabola.
