((y+3)^2)/(81)+((x-7)^2)/(64)=1

\frac{( y + 3 ) ^{2}}{81} + \frac{( x - 7 ) ^{2}}{64} = 1

(h, k) = (7, - 3), a = 8, b = 9

Solution steps

\frac{( y + 3 ) ^{2}}{81} + \frac{( x - 7 ) ^{2}}{64} = 1

Rewrite

\frac{( y + 3 ) ^{2}}{81} + \frac{( x - 7 ) ^{2}}{64} = 1

in the form of the standard ellipse equation

\frac{( x - 7 ) ^{2}}{8 ^{2}} + \frac{( y - ( - 3 ) ) ^{2}}{9 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (7, - 3), a = 8, b = 9

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (7, - 3), b = 9, a = 8
