((x+1)^2)/9+((y-2)^2)/(sqrt(8^2))=1

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

(h, k) = (- 1, 2), a = 3, b = 22

Solution steps

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

Rewrite

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

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (- 1, 2), a = 3, b = 22

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (- 1, 2), a = 3, b = 22

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

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

\frac{( x + 1 ) ^{2}}{64} + \frac{( y - 1 ) ^{2}}{100} = 1

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

\frac{x ^{2}}{24} + \frac{y ^{2}}{20} = 1
