\n" ); document.write( "\n" ); document.write( "First let's find the slope of the line through the points and \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Note: is the first point . So this means that \"x%5B1%5D=-4\" and \"y%5B1%5D=-5\".\r
\n" ); document.write( "\n" ); document.write( "Also, is the second point . So this means that \"x%5B2%5D=-4\" and \"y%5B2%5D=5\".\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=%285--5%29%2F%28-4--4%29\" Plug in \"y%5B2%5D=5\", \"y%5B1%5D=-5\", \"x%5B2%5D=-4\", and \"x%5B1%5D=-4\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%2810%29%2F%28-4--4%29\" Subtract \"-5\" from \"5\" to get \"10\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%2810%29%2F%280%29\" Subtract \"-4\" from \"-4\" to get \"0\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Remember, you cannot divide by zero. So this means that the slope is undefined.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the slope is undefined, this means that the equation of the line through the points and is \"x=-4\".\r
