The isometry here is a translantion,Originally Posted by Stuart

Your mistake it that you used the translation,
For ((X^2)/ 9) + ((Y^2)/16) = 1
the general form after 4 units right and 2 units down would be:
16x^2 + 9y^2 - 128x +36y + 148 = 0 Yes/No
and for the equation (((x-2)^2)\4) + (((y-3)^2)/16) = 1
the standard equation would be?
