You can put this solution on YOUR website!
Note: is the first point . So this means that \"x%5B1%5D=-19\" and \"y%5B1%5D=-10\".\r
\n" ); document.write( "\n" ); document.write( "Also, is the second point . So this means that \"x%5B2%5D=-20\" and \"y%5B2%5D=-15\".\r
\n" ); document.write( "
\n" ); document.write( "
\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( "\n" ); document.write( "\"m=%28-15--10%29%2F%28-20--19%29\" Plug in \"y%5B2%5D=-15\", \"y%5B1%5D=-10\", \"x%5B2%5D=-20\", and \"x%5B1%5D=-19\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-5%29%2F%28-20--19%29\" Subtract \"-10\" from \"-15\" to get \"-5\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-5%29%2F%28-1%29\" Subtract \"-19\" from \"-20\" to get \"-1\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=5\" Reduce\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the slope of the line that goes through the points and is \"m=5\"\r
