In words:
\n" ); document.write( "( endpoint #1 + endpoint #2) / 2 = midpoint
\n" ); document.write( "You need to use this formula twice, once for
\n" ); document.write( "x-coordinates, and again for the y -coordinates
\n" ); document.write( "----------------------------------
\n" ); document.write( "suppose the endpoints are:
\n" ); document.write( "(0,1) and (7,5)
\n" ); document.write( "(7 + 0)/2 = 7/2
\n" ); document.write( "and
\n" ); document.write( "(5 + 1)/2 = 3
\n" ); document.write( "The midpoint is (7/2 , 3)
\n" ); document.write( "--------------------
\n" ); document.write( "To check, the equation that includes the endpoints is
\n" ); document.write( " $\"%28y+-+1%29%2F%28x+-+0%29+=+%285+-+1%29%2F%287+-+0%29\"$
\n" ); document.write( " $\"%28y+-+1%29%2Fx+=+4%2F7\"$
\n" ); document.write( " $\"y+-+1+=+%284x%29%2F7\"$
\n" ); document.write( " $\"y+=+%284%2F7%29%2Ax+%2B+1\"$
\n" ); document.write( "Does it include the midpoint?
\n" ); document.write( " $\"+3+=+%284%2F7%29%2A%287%2F2%29+%2B+1\"$
\n" ); document.write( " $\"3+=+2+%2B+1\"$
\n" ); document.write( " $\"3+=+3\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
