Answer:
Put the green dot on 0. Then, make the numbers 0 threw -5 have a blue line. Make sure the blue line touches the arrow at the end of the number line, next to -5.
Explanation:
It is saying x is equal to or less than 0.
X can be any number starting at 0, moving left.
An open dot means the number can not equal the number it is comparing. In this case, it should be closed.
I hope this makes sence!
