y=-2x
\n" ); document.write( "x^2+(-2x)^2=4
\n" ); document.write( "x^2+4x^2=4
\n" ); document.write( "5x^2=4
\n" ); document.write( "x^2=4/5
\n" ); document.write( "x=+-2/sqrt(5)\r
\n" ); document.write( "\n" ); document.write( "x=+2sqrt(5)/5
\n" ); document.write( "x=-2sqrt(5)/5\r
\n" ); document.write( "\n" ); document.write( "y=-2x\r
