You can put this solution on YOUR website!
y=2x+2 is a straight line that crosses the x-axis at -1 (the root you found in your working out). Where does it cross the y-axis? this is where x=0, so put x=0 into the equation, and we get y=2(0) + 2 --> y=2.\r
\n" ); document.write( "\n" ); document.write( "So draw a set of axis. Plot the 2 points (-1,0) and (0,2) and get a ruler and join them.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "As for y<2x+2.. it is everything \"less than\"...so all the space below the line.
\n" ); document.write( "As for y>2x+2.. it is everything \"greater than\"...so all the space above the line.\r
