axis ((x-2)^2)/9+((y-1)^2)/(25)=1

axis

\frac{( x - 2 ) ^{2}}{9} + \frac{( y - 1 ) ^{2}}{25} = 1

semi - major axis b = 5, semi - minor axis a = 3

Solution steps

\frac{( x - 2 ) ^{2}}{9} + \frac{( y - 1 ) ^{2}}{25} = 1

Rewrite

\frac{( x - 2 ) ^{2}}{9} + \frac{( y - 1 ) ^{2}}{25} = 1

in the form of the standard ellipse equation

\frac{( x - 2 ) ^{2}}{3 ^{2}} + \frac{( y - 1 ) ^{2}}{5 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (2, 1), a = 3, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (2, 1), b = 5, a = 3

4 x^{2} + y^{2} + 16 x + 4 y + 4 = 0

5 x^{2} + 2 y^{2} = 50

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

\frac{( x - 5 ) ^{2}}{36} + \frac{( y - 1 ) ^{2}}{16} = 1

\frac{( x - 2 ) ^{2}}{4} + \frac{( y - 3 ) ^{2}}{1} = 1
