Rate of change is computed using slope:\r
\n" ); document.write( "\n" ); document.write( "m=(y2-y1)/(x2-x1)
\n" ); document.write( "so
\n" ); document.write( "m=(2-1)/(4-8)=-1/4\r
\n" ); document.write( "\n" ); document.write( "that means the rate is falling at 0.25 inches every month
\n" ); document.write( "
\n" );
