Note: is the first point and is the second point .\r

\n" ); document.write( "\n" ); document.write( "\"m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\" Start with the slope formula.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-19--12%29%2F%28-17--16%29\" Plug in \"y%5B2%5D=-19\", \"y%5B1%5D=-12\", \"x%5B2%5D=-17\", and \"x%5B1%5D=-16\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-7%29%2F%28-17--16%29\" Subtract \"-12\" from \"-19\" to get \"-7\"\r
