center x^2+(y^2)/9 =1

center

x^{2} + \frac{y ^{2}}{9} = 1

(0, 0)

Solution steps

x^{2} + \frac{y ^{2}}{9} = 1

Rewrite

x^{2} + \frac{y ^{2}}{9} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{1 ^{2}} + \frac{( y - 0 ) ^{2}}{3 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 1, b = 3

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, 0), b = 3, a = 1

And the center is:

(0, 0)

\frac{( x + 1 ) ^{2}}{1} + \frac{( y - 2 ) ^{2}}{4} = 1

x^{2} + 10 x + 9 y^{2} + 16 = 0

9 x^{2} + 16 y^{2} - 18 x - 64 y - 71 = 0

3 x^{2} + 4 y^{2} + 24 x - 16 y + 52 = 0

\frac{y ^{2}}{16} + \frac{x ^{2}}{9} = 1
