You can put this solution on YOUR website!
Suppose you are given 2 coordinates: A (x1,y1) and B (x2,y2). We can find the slope with the dollowing equation:
\n" ); document.write( "\"m+=+%28y2-y1%29%2F%28x2-x1%29\"
\n" ); document.write( "--
\n" ); document.write( "EX: A(1,4) B (-3,9)
\n" ); document.write( "using the slope formula we get
\n" ); document.write( "\"m+=+%289-4%29%2F%28-3-1%29\" = 5/-4
\n" ); document.write( "so
\n" ); document.write( "m = -5/4
\n" ); document.write( "
\n" );
