\"slope=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29\"
\n" ); document.write( "where the \"x\" is the horizontal distance (in inches) to the sewer main,
\n" ); document.write( "and \"y\" is the height (in inches).
\n" ); document.write( "We can make point \"P%5B1%5D\"(\"x%5B1%5D\",\"y%5B1%5D\") the connection at the main,
\n" ); document.write( "and \"P%5B2%5D\"(\"x%5B2%5D\",\"y%5B2%5D\") the connection at the house.
\n" ); document.write( "
\n" ); document.write( "\"slope=%28-6-%28-18%29%29%2F%2848%2A12-0%29=12%2F48%2F12=1%2F48\"
\n" ); document.write( "That tells us that going from the main to the house the pipe would go up 1 inch as it goes forward 48.
\n" ); document.write( "Since \"1%2F48=about0.02\"= 2%, maybe they call that a 2% slope.
\n" ); document.write( "Or maybe there are regulations for slope of the sewer lines, and maybe they measure the slope in inches per foot, so that would be
\n" ); document.write( "\"12inches%2F%2248+feet%22=0.25\"\"inch%2Ffoot\"
\n" ); document.write( "
