You can put this solution on YOUR website!

\n" ); document.write( "

\r\n" );
document.write( "Take the second equation  y = ax + 5  and substitute x= 6,  y= -1  into it.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You will get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    -1 = a*6 + 5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It implies\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    -1 - 5 = 6a\r\n" );
document.write( "\r\n" );
document.write( "    -6     = 6a\r\n" );
document.write( "\r\n" );
document.write( "     a     =  = -1.      ANSWER\r\n" );
