Note: is the first point . So this means that \"x%5B1%5D=-5\" and \"y%5B1%5D=4\".\r
\n" ); document.write( "\n" ); document.write( "Also, is the second point . So this means that \"x%5B2%5D=15\" and \"y%5B2%5D=-4\".\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=%28-4-4%29%2F%2815--5%29\" Plug in \"y%5B2%5D=-4\", \"y%5B1%5D=4\", \"x%5B2%5D=15\", and \"x%5B1%5D=-5\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-8%29%2F%2815--5%29\" Subtract \"4\" from \"-4\" to get \"-8\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28-8%29%2F%2820%29\" Subtract \"-5\" from \"15\" to get \"20\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=-2%2F5\" 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=-2%2F5\"
