Question 798893
<font face="Times New Roman" size="+2">


The equation of an ellipse centered at *[tex \Large (h,\,k)] and with semi-major axis *[tex \Large a] and semi-minor axis *[tex \Large b] is either:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{\left(x\ -\ h\right)^2}{a^2}\ +\ \frac{\left(y\ -\ k\right)^2}{b^2}\ =\ 1] 


or


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{\left(x\ -\ h\right)^2}{b^2}\ +\ \frac{\left(y\ -\ k\right)^2}{b^2}\ =\ 1]


It might help to rewrite your equation thus:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{\left(x\ -\ 8\right)^2}{7^2}\ +\ \frac{\left(y\ -\ (-6)\right)^2}{11^2}\ =\ 1]
