You can put this solution on YOUR website! I would plot these two. Both are lines. Then find the area between the lines that satisfies the two inequalities.
Plot the line y = 2x + 6
Now draw another line at y=-5 (horizontal line). The solution is all the area between the two lines, including the top line, that lies above y=-5. So it is a 'wedge' going out from the point (-5.5, -5) toward the right.
Make sense?
