This is what I did but I don't think its right and If it is, i don't know where to go from there to get the other points.
\n" ); document.write( "x=2-7y
\n" ); document.write( "5(2-7y) + 6y=1
\n" ); document.write( "10-35y + 6y=1
\n" ); document.write( "-29y= -9

\n" ); document.write( "-------------
\n" ); document.write( "YOU ARE CORRECT
\n" ); document.write( "I graphed it with a graphing calculator.
\n" ); document.write( "Your x,y values are the point of intersection.
