Plot the graph of:\r
\n" ); document.write( "\n" ); document.write( "(9,3)\r
\n" ); document.write( "\n" ); document.write( "(3,-6)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rise/run = 9/6 = 3/2 = 1 1/2\r
\n" ); document.write( "\n" ); document.write( "The Slope is: 3/2 (or 1 1/2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The other method:\r
\n" ); document.write( "\n" ); document.write( "(y2 - y1)/(x2 - x1) = 3 - (-6) / 9 - 3\r
\n" ); document.write( "\n" ); document.write( "3 - (-6) = 3 + 6 = 9\r
\n" ); document.write( "\n" ); document.write( "9 - 3 = 6\r
\n" ); document.write( "\n" ); document.write( "Therefore:\r
\n" ); document.write( "\n" ); document.write( "9/6 = 3/2 = 1 1/2\r
\n" ); document.write( "\n" ); document.write( "The Slope is: 3/2 (1 1/2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The Equation of the Line is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 1 1/2x - 10 1/2\r
\n" ); document.write( "
