\"slope=rise%2Frun\" Start with the slope formula. The \"rise\" is the change in vertical position and the \"run\" is the change in horizontal position.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"slope=2.6%2F7.5\" Plug in the given values\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"slope=0.34667\" Divide\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the slope is approximately \"0.34667\" which means that the grade is roughly 34.667% (multiply by 100 to make a percentage)
\n" ); document.write( "
\n" );
