    No no. Not that. See your set is all the number lesser than -6. Which means 6 is not in the set of your solution. However, you can say -5.99999........ is in the set of solution. So how do you represent that on a number line. Somehow you will have to show that you have excluded -6 but you have included all values lesser than that.

    So mathematicians use this clever method to do that. What they do, is circle -6 and leave the circle empty. Which means -6 is not included. Now they draw a line along the numbers lesser than -6, which shows it includes all numbers lesser than -6

    I am sorry, I have mentioned that -5.999999 is in the set of solution. Please exchange that number with -6.00000000001. I mistyped it. Sorry
