    \[\huge\rm \frac{ (x-h)^2 }{ a^2 } +\frac{ (y-k)^2 }{ b^2 }\] standard form of ellipse if a is under the x then it would be horizontal and if a is under y then graph would be vertical |dw:1439072800559:dw||dw:1439072820181:dw|

    by just looking at the standard form of the equation you can eliminate 2 answer choices

    \[\huge\rm \frac{ (x-y)^2 }{ a^2 } - \frac{ (y-k)^2 }{ b^2 }\] this is standard form equation of *hyperbola* only difference is the sign between both fractions

    |dw:1439073497169:dw|\[\huge\rm \frac{ (x-y)^2 }{ a^2 } - \frac{ (y-k)^2 }{ b^2 }\] this is standard form equation of *hyperbola* that's how the graph looks like

    and here is graph of ellipse equation |dw:1439073570566:dw|\[\huge\rm \frac{ (x-y)^2 }{ a^2 } \color{reD}{+} \frac{ (y-k)^2 }{ b^2 }\]

    yes right so bigger number should be under the y value and there is plus sign so that's right!

    my pleasure. B and D can't be the answer bec those 2 are hyperbola equations
