Let the coordinates of L be:
\n" ); document.write( "L( x[1], y[1] )
\n" ); document.write( "--------------
\n" ); document.write( " $\"+%28+-7+%2B+x%5B1%5D+%29+%2F+2+=+-4+\"$
\n" ); document.write( " $\"+-7+%2B+x%5B1%5D+=+-8+\"$
\n" ); document.write( " $\"+x%5B1%5D+=+-1+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+%28+-3+%2B+y%5B1%5D+%29+%2F+2+=+-6+\"$
\n" ); document.write( " $\"+-3+%2B+y%5B1%5D+=+-12+\"$
\n" ); document.write( " $\"+y%5B1%5D+=+-9+\"$
\n" ); document.write( "-----------------
\n" ); document.write( "L( x[1], y[1] ) = L( -1, -9 )
\n" ); document.write( "is the other endpoint \n" ); document.write( "
