Question

What is the equation of the following graph?
Answers:
(x+2)2/9+(y+2)2/4=1
(x-2)2/4+(y-2)2/9=1
(x-2)2/9-(y-2)2/4=1
(x-2)2/9+(y-2)2/4=1

Answer 1

it is translated +2 right, +2 up

Answer 2

so you must have something like :-

(x-2)^2/a^2 + (y-2)^2/b^2 = 1

Answer 3

First part: Where is the center of the ellipse?
Since the major axis is horizontal, the standard form is:
\[\frac{ (x-h)^2 }{ a^2 } + \frac{ (y-k)^2 }{ b^2 } = 1\]
Where (h,k) is the center, a is half the length of the major axis, and b is half the length of the minor axis.
