You can put this solution on YOUR website!
4(x+1)^2 + 9(y-1)^2 = 36
\n" ); document.write( "----
\n" ); document.write( "Convert to standard form:
\n" ); document.write( "[(x+1)^2]/9 + [(y-1)^2]/4 = 1
\n" ); document.write( "---------------------
\n" ); document.write( "Do you see that the center is at (-1,1) ?
\n" ); document.write( "----
\n" ); document.write( "Do you see that the semi-major axis is sqrt(9) = 3
\n" ); document.write( "so the right-most vertex is at (2,1) and the left-most
\n" ); document.write( "vertex is at (-4,1) ?
\n" ); document.write( "-----
\n" ); document.write( "Do you see that the semi-minor axis is sqrt(4) = 2
\n" ); document.write( "so the top vertex is at (-1,3) and the bottom vertex
\n" ); document.write( "is at (-1,-1) ?
\n" ); document.write( "=======================
\n" ); document.write( "If you see all that, you can sketch the ellipse.
\n" ); document.write( "=======================
