\n" ); document.write( "Y=4x+1
\n" ); document.write( "that is:
\n" ); document.write( " 4x+1 = x-2
\n" ); document.write( " 3x = -3
\n" ); document.write( " x = $\"highlight%28-1%29\"$ and y = $\"highlight%28+-3%29\"$ $\"-1-2\"$
\n" ); document.write( "Checking
\n" ); document.write( " $\"Y=4x%2B1\"$
\n" ); document.write( " - 3 =4( -1) + 1
\n" ); document.write( " -3 = -4 + 1
\n" ); document.write( "-3 = -3 Checks! \n" ); document.write( "
