Graph the ellipses
\n" ); document.write( "49((y-2)^2-1)=-(x+3)^2
\n" ); document.write( "49(y-2)^2-49=-(x+3)^2
\n" ); document.write( "49(y-2)^2+(x+3)^2=49
\n" ); document.write( "divide by 49
\n" ); document.write( "(y-2)^2+(x+3)^2/49=1
\n" ); document.write( "(x+3)^2/49+(y-2)^2=1
\n" ); document.write( "This is an equation of an ellipse with horizontal major axis.
\n" ); document.write( "Its standard form: (x-h)^2/a^2+(y-k)^2/b^2=1,a>b, (h,k)=(x,y) coordinates of center
\n" ); document.write( "For given equation:
\n" ); document.write( "center: (-3,2)
\n" ); document.write( "a^2=49
\n" ); document.write( "a=√49=7
\n" ); document.write( "length of horizontal major axis=2a=14
\n" ); document.write( "..
