(x/9)^2+(y/4)^2=1

(\frac{x}{9})^{2} + (\frac{y}{4})^{2} = 1

(h, k) = (0, 0), a = 9, b = 4

Solution steps

(\frac{x}{9})^{2} + (\frac{y}{4})^{2} = 1

Rewrite

(\frac{x}{9})^{2} + (\frac{y}{4})^{2} = 1

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{9 ^{2}} + \frac{( y - 0 ) ^{2}}{4 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 9, b = 4

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 9, b = 4

2 x^{2} + y^{2} - 5 = 1

5 (x + 1)^{2} + 3 y^{2} = 15

4 y^{(2)} + 2 x^{(2)} + 48 y + 4 x - 22 = 0

\frac{( x - 2 ) ^{2}}{25} + \frac{( y - 3 ) ^{2}}{16} = 1

\frac{( x - 3 ) ^{2}}{16} + \frac{( y + 2 ) ^{2}}{9} = 1
