Find the slope: x + 3y = -9\r
\n" ); document.write( "\n" ); document.write( "3y = -9 - x\r
\n" ); document.write( "\n" ); document.write( "Divide each item by 3\r
\n" ); document.write( "\n" ); document.write( "3y/3 = -9/3 - x/3\r
\n" ); document.write( "\n" ); document.write( "y = -3 - x/3\r
\n" ); document.write( "\n" ); document.write( "Drawing the graph the x and y values are:\r
\n" ); document.write( "\n" ); document.write( "(-6,-1)\r
\n" ); document.write( "\n" ); document.write( "(-3,-2)\r
\n" ); document.write( "\n" ); document.write( "(0,-3)\r
\n" ); document.write( "\n" ); document.write( "(3,-4)\r
\n" ); document.write( "\n" ); document.write( "(6,-5)\r
\n" ); document.write( "\n" ); document.write( "The slope = rise/run = -2/6 = -1/3\r
\n" ); document.write( "\n" ); document.write( "The other method to find the slope is:\r
\n" ); document.write( "\n" ); document.write( "(y2 - y1)/(x2 - x1)\r
\n" ); document.write( "\n" ); document.write( "(-4 - (-3))/(3 - 0)\r
\n" ); document.write( "\n" ); document.write( "-4 + 3 = -1\r
\n" ); document.write( "\n" ); document.write( "3 - 0 = 3\r
\n" ); document.write( "\n" ); document.write( "= -1/3\r
\n" ); document.write( "\n" ); document.write( "The Slope: -1/3 \n" ); document.write( "

\n" );
