Yep you are rightt!!! You are awesome and smart!!
Btw, do you think we need to know the foci, and directix for the ellipse without the origin (0,0) center.
bumping for posterity-make sure you know these formulas!
MANNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN!! ARE YOU SERIOUS!!?
