find parabola eqn, given focus, directrix / etc.

[BingBong20]

1. Write the equation of the parabola given the focus at (-3,-2) and the directrix is the line y=-6. It is helpful to draw a sketch of what is given to help in choosing the correct formula. Be sure you have the correct formula to fill in. leave the equation in standard form.

2.Given the ellipse equation 9x^2 + 4y^2-18x + 16y=0 , find the coordinates of the center, the vertices, and the foci. Sketch the ellipse on the grid showing each of these points as dots. Show steps for converting to standard form.

PLEASE INCLUDE ANY WORK STEP BY STEP. I HAVE ANSWERS OF MY OWN BUT TRYING TO DOUBLE CHECK THEM TO SEE WHAT I DID WRONG.

THANK YOU

Hmmmm.....the wording of these questions looks suspiciously like what one would see on a test.

Since you say you have "answers of my own, but trying to double check them," I suggest that you show US step by step what you did. We'd be glad to check your work.
