: I have no idea how to do anything with conics, our teacher is not the best teacher and my question is, how to write an equation for the conic section- Ellipse with vertices at (-2,2) and (4,2) and co-vertices at (1,1) and (1,3) This question is from textbook

You can put this solution on YOUR website!
We can tell that the center is at (1,2) in (h,k) form.
The distance from the center to the farthest verticies is a.
The distance from the center to the closest certicies is b.
a+=+3
b+=+1
Equation for horizontal Ellipse:
%28x+-+h%29%5E2%2Fa%5E2+%2B+%28y+-+k%29%5E2%2Fb%5E2+=+1
%28x+-+1%29%5E2%2F9+%2B+%28y+-+2%29%5E2%2F1+=+1
