You can put this solution on YOUR website!
which two has the same x corridence NOTE: it does not matter if they are both negative or one positive the other negative.\r
\n" ); document.write( "\n" ); document.write( "next which two has the same y coordinance?\r
\n" ); document.write( "\n" ); document.write( "y = -9x+1
\n" ); document.write( "y = 9x+1
\n" ); document.write( " these two are parrallel
\n" ); document.write( "
\n" );
