axis 16x^2-64x+9y^2-54y=-1

axis

semi - major axis b = 4, semi - minor axis a = 3

Solution steps

16 x^{2} - 64 x + 9 y^{2} - 54 y = - 1

Rewrite

16 x^{2} - 64 x + 9 y^{2} - 54 y = - 1

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (2, 3), a = 3, b = 4

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (2, 3), b = 4, a = 3
