To graph \"y=-8x\", we need to plot a series of points.\r

\n" ); document.write( "\n" ); document.write( "To get a series of points, we need to plug in various values of x to get corresponding values of y.\r

\n" ); document.write( "\n" ); document.write( "Plug in \"x+=+-2\" to find y\r

\n" ); document.write( "\n" ); document.write( "When \"x+=+-2\", \"y+=+16\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we have the point (-2, 16)\r
