You can put this solution on YOUR website!
Let the other endpoint be ( a, b )
\n" ); document.write( "I can say:
\n" ); document.write( "(1) $\"+%28+-5+%2B+b+%29+%2F+2+=+-7+\"$
\n" ); document.write( "(2) $\"+%28+-5+%2B+a+%29+%2F+2+=+-10+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "(1) $\"+-5+%2B+b+=+-14+\"$
\n" ); document.write( "(1) $\"+b+=+-9+\"$
\n" ); document.write( "and
\n" ); document.write( "(2) $\"+-5+%2B+a+=+-20+\"$
\n" ); document.write( "(2) $\"+a+=+-15+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "The othrr endpoint is at ( -15, -9 )\r
