If you were to graph the solution, the arrow would be going to the left. I know this because the the less than symbol in the answer is pointing to the left. It's kinda hard to tell, but that's the way I figure it out every time. Also, the circle you draw will not be shaded in because the symbol in the answer is greater than or equal to/less than or equal to.
Let me know if any of what I said doesn't make sense. I hope I could help!
