\n" ); document.write( "\n" ); document.write( "3x+y=7
\n" ); document.write( "y=-3x+7\r
\n" ); document.write( "\n" ); document.write( "compare with y= mx+b
\n" ); document.write( "m= -3 passing through (2,-1)
\n" ); document.write( "The slope of parallel line will be the same. m=-3\r
\n" ); document.write( "\n" ); document.write( "plug the values in y=mx+b
\n" ); document.write( "-1=-3*2+b
\n" ); document.write( "-1=-6+b
