Thread: One yes or no and one ellipse equation

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?

The isometry here is a translantion,

Thus,

Becomes,

Thus,

Thus,

Thus,

Your mistake it that you used the translation,

ok so how would I start the second equation listed?

By the previous post you have,
