This way of showing generalized standard form if parallel to the x-axis:
\n" ); document.write( "\"x-h=a%28y-k%29%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You will use the point (7,1) to find a, and also use the given vertex h=2, k=5.
\n" ); document.write( "\"a%28y-k%29%5E2=x-h\"
\n" ); document.write( "\"a=%28x-h%29%2F%28y-k%29%5E2\"
\n" ); document.write( "\"a=%287-2%29%2F%281-5%29%5E2\"
\n" ); document.write( "\"a=5%2F%28-4%29%5E2\"
\n" ); document.write( "\"a=5%2F16\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Put in the values into the form:
\n" ); document.write( "\"highlight%28x-2=%285%2F16%29%28y-5%29%5E2%29\" or if you want, \"highlight%28x=%285%2F16%29%28y-5%29%5E2%2B2%29\".
\n" ); document.write( "
\n" );
