SOLUTION: Graph each ellipse and clearly indicate the center, foci, vertices, and co-vertices
x^2/16 - x/4 + y^2/9 + 4y/9 = 11/16
PS This is on fractions!! Thank you!'

..........complete squares
-> and , so the center is at (, )
semi-major axis length:
≈
semi-minor axis length:≈
foci: (, ) =(, ) ≈ (, )
and
foci :(, ) =(,) ≈ (,)
vertices:
The vertices are units above and below the center, at
(, ) ≈ (, )
and
(, ) ≈ (, )
The co-vertices are units to either side of the center, at
( , ) and (, )

Center: (2,-2) where the black lines (the ellipse's axes of symmetry) cross
: , : ,
approximately (2,-5.527) and (2,1.527)
: ,
approximately (-1.110,-2) and (5.110,-2).
