Best ResponseYou've already chosen the best response.3let's consider a new coordinate system X,Y located at point (0,2), namely at the center of your ellipse

Best ResponseYou've already chosen the best response.3oops.. I made a typo, the center of our ellipse is located at poin (0,2)

Best ResponseYou've already chosen the best response.3and the equations of our traslation are: \[\Large \left\{ \begin{gathered} x = X \hfill \\ y = Y  2 \hfill \\ \end{gathered} \right.\]

Best ResponseYou've already chosen the best response.3hint: we have this: \[\Large X = x\] right?

Best ResponseYou've already chosen the best response.3namely into this equation: \[\Large \frac{{{X^2}}}{1} + \frac{{{Y^2}}}{9} = 1\] what equation do you get?

Best ResponseYou've already chosen the best response.3hint: \[\Large \frac{{{x^2}}}{1} + \frac{{{{\left( {y + 2} \right)}^2}}}{9} = 1\] is it right?

Best ResponseYou've already chosen the best response.0For shifted one, you need center (h, k), the way to find out a, b as what we had done before. The way a goes with major axis is the same. Just the numerators change to (xh) ^2 and (yk)^2. Dat sit.
