You can simplify this by subtracting x from both sides.  Then you have 4y = 8x.  Now, y = x would be a straight line, angled at 45 deg, starting at 0, 0 and, passing through an point like 1, 1; 2, 2; 12, 12...etc.<BR>\n" );

document.write( "That looks a lot like y = x that we already decided is a straight line.  The expression we have in this problem, y = 2x would like similar, but be steeper line passing through the points: 0, 0; 2, 1; 4, 2; 8, 4; etc.<BR>\n" );
