## katlin95 2 years ago can somebody graph the number line of -x/3 greater than or equal to 2? using open and closed circles?

1. katlin95

i know i wanna see if your answer matches with wat i got

2. katlin95

i know, I was gona draw it, ns then have one of you see if it was correct, no need to be rude!

3. Infinyte

hang on i have it

4. JuanitaM

Katlin, what did you get for your equation of your line? that is a good starting point.

5. Mertsj

First multiply both sides by 3 to get rid of the fraction.

6. katlin95

I just have to put it on a number line using either an open or closed circle

7. katlin95

this is what I got for an answer.

9. JuanitaM

Yes, but in order to put on a line it should be in the proper equation. Rewrite your given problem so that x is on one side.

10. JuanitaM

your -6 is correct, but your inequality sign should have been switched.

11. JuanitaM

|dw:1359404971367:dw|

12. katlin95

so it should be an open circle then instead of a closed circle right?

13. JuanitaM

What is the difference b/w open and closed?

14. Mertsj

< or > means open circle <= or >= means closed circle

15. JuanitaM

as a hint, closed is "inclusive" so if you have = to also, than it is closed. Your direction is what I was getting you to change....

16. katlin95

correct, so then it would be an open circle right?

17. JuanitaM

no closed as you had it

18. katlin95

okay so the number line i gave u was correct right?

19. JuanitaM

|dw:1359405268095:dw|

20. JuanitaM

yes - you just had the line going in the wrong direction.....final equation is less than or equal to so therefore your lines goes to the left

21. katlin95

last one: how about this one? Which of the following is the correct graph of the inequality -2x < 8?

22. katlin95

Which of the following is the correct graph of the inequality -2x < 8? this is my answer

23. JuanitaM

Absolutely correct. Great job !

hey thanks for helping me out!:)
