After plotting the straight line graph of:\r
\n" ); document.write( "\n" ); document.write( "(2,-1)\r
\n" ); document.write( "\n" ); document.write( "(6,3)\r
\n" ); document.write( "\n" ); document.write( "The Slope = rise/run = 4/4 = 1\r
\n" ); document.write( "\n" ); document.write( "The other method:\r
\n" ); document.write( "\n" ); document.write( "(y2 - y1)/(x2 - x1)\r
\n" ); document.write( "\n" ); document.write( "3 - (-1)/6 -2\r
\n" ); document.write( "\n" ); document.write( "3 - (-1) = 3 + 1 = 4\r
\n" ); document.write( "\n" ); document.write( "6 -2 = 4\r
\n" ); document.write( "\n" ); document.write( "4/4 = 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "or\r
\n" ); document.write( "\n" ); document.write( "-1 - 3/2 - 6\r
\n" ); document.write( "\n" ); document.write( "-1 - 3 = -4\r
\n" ); document.write( "\n" ); document.write( "2 - 6 = -4\r
\n" ); document.write( "\n" ); document.write( "-4/-4 = 4/4 = 1\r
\n" ); document.write( "\n" ); document.write( "Therefore:\r
\n" ); document.write( "\n" ); document.write( "The Slope - m = 1\r
