\n" ); document.write( "Center (2,5) and one end of minor axis (2,3) means the minor axis is vertical, so the general equation is

\n" ); document.write( " $\"%28x-h%29%5E2%2Fa%5E2%2B%28y-k%29%5E2%2Fb%5E2=1\"$

\n" ); document.write( "The center is (h,k); a is the semi-major axis; b is the semi-minor axis.

\n" ); document.write( "The center (h,k) is given.
\n" ); document.write( "The length of the major axis is 12, so a = 6.
\n" ); document.write( "The length of the semi-minor axis, b, is the distance from (2,5) to (2,3), which is 2.

\n" ); document.write( "So

\n" ); document.write( " $\"%28x-2%29%5E2%2F6%5E2%2B%28y-5%29%5E2%2F2%5E2=1\"$

\n" ); document.write( "ANSWER: $\"%28x-2%29%5E2%2F36%2B%28y-5%29%5E2%2F4=1\"$

\n" ); document.write( " \n" ); document.write( "
