Hello,

rearrange your equations until you can determine the type of conic. All of them have their axes parallel to the coordinate axes so completing the square will do:

to #1:

That's a parabola opening down.

to #2:

. Now divide by 24 and you'll get:

That's the equation of an ellipse.

The ##3 to 5 should be done similary.(H, H, E)
