You can put this solution on YOUR website!
the points are:
\n" ); document.write( "(x1,y1) , (x2,y2)
\n" ); document.write( "The formula is:
\n" ); document.write( " $\"+%28y+-+y1%29+%2F+%28x+-+x1%29+=+%28y2+-+y1%29+%2F+%28x2+-+x1%29+\"$
\n" ); document.write( "given:
\n" ); document.write( "(4,1) (6,3)
\n" ); document.write( " $\"+%28y+-+1%29+%2F+%28x+-+4%29+=+%283+-+1%29+%2F+%286+-+4%29+\"$
\n" ); document.write( " $\"+%28y+-+1%29+%2F+%28x+-+4%29+=+1+\"$
\n" ); document.write( " $\"+y+-+1+=+x+-+4\"$
\n" ); document.write( " $\"y+=+x+-+3\"$
\n" ); document.write( "check answer:
\n" ); document.write( "(6,3)
\n" ); document.write( " $\"y+=+x+-+3\"$
\n" ); document.write( " $\"3+=+6+-+3\"$
\n" ); document.write( " $\"3+=+3\"$
\n" ); document.write( "OK
\n" ); document.write( "(4,1)
\n" ); document.write( " $\"y+=+x+-+3\"$
\n" ); document.write( " $\"1+=+4+-+3\"$
\n" ); document.write( " $\"1+=+1\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
