So yeah, I'm quite confused on this one equation. I get how to find the points of ellipses when they are in the form of (x-5)^2/(9)+(y-3)^2/(9)=1

But i'm having trouble finding out how to find the points for when there is a number in front of the parentheses.

This is the problem.


I know you divide the 100 by 100 to get it to equal 1
but after that idk what to do with the 4 and 25? HELP!
