Is this in standard form for an ellipse?

OpenStudy (anonymous):

\[(x+1)^{2}+9(y-6)^{2}=9\]

OpenStudy (anonymous):

No, I don't think it is, sir

OpenStudy (anonymous):

when i distributed i got\[x ^{2}+1+9y ^{2}+324=9\] oh wait its not a circle

OpenStudy (anonymous):

thats an ellipse !

OpenStudy (anonymous):

oh sorry i wrote ellipse above, forgot to fix the question

ganeshie8 (ganeshie8):

\[\large (x+1)^{2}+9(y-6)^{2}=9\] divide thru by 9 : \[\large \dfrac{(x+1)^{2}}{9}+\dfrac{(y-6)^{2}}{1}=1\]

OpenStudy (anonymous):
