((x+1)^2)/(16)+((y+1)^2)/(25)=1

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

(h, k) = (- 1, - 1), a = 4, b = 5

Solution steps

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

Rewrite

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

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{4 ^{2}} + \frac{( y - ( - 1 ) ) ^{2}}{5 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, - 1), a = 4, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 1, - 1), b = 5, a = 4

\frac{x ^{2}}{256} + \frac{y ^{2}}{400} = 1

\frac{( x - 1 ) ^{2}}{13} + \frac{( y + 5 ) ^{2}}{12} = 1

x^{2} + 2 y^{2} - 8 y - 32 = 0

\frac{x ^{2}}{324} + \frac{y ^{2}}{400} = 1

3 x^{2} + 4 y^{2} - 12 x = 36
