All reactions WebbYour ellipse has its major axis aligned with (I’m assuming) the line y = x, in other words it has symmetry x ↔ y. This means that it has an equation of the shape a ( x 2 + y 2) + b x y + c ( x + y) = 1, and since you’ve specified that the center is at the origin, you also need c = 0. Thus your equation will simply be a ( x 2 + y 2) + b x y 1. graphic good night
