25(x-1)^2 + 9(y+3)^2=225 identify the curve?
\n" ); document.write( "put in standard form then identify the curve.
\n" ); document.write( "**
\n" ); document.write( "standard form for an ellipse with vertical major axis:
\n" ); document.write( " $\"%28x-h%29%5E2%2Fb%5E2%2B%28y-k%29%5E2%2Fa%5E2=1\"$ , a>b, (h,k)=(x,y) coordinates of center
\n" ); document.write( " $\"25%28x-1%29%5E2%2B9%28y%2B3%29%5E2=225\"$
\n" ); document.write( "divide both sides by 225
\n" ); document.write( " $\"%28x-1%29%5E2%2F9+%2B+%28y%2B3%29%5E2%2F25=1\"$
\n" ); document.write( "Given equation is that an ellipse with vertical major axis and center at (1,-3)
