Hi there!
For these number lines, the area from the point to where the arrow is pointing onwards is the part included in the inequality.
We see that what is included is anything less than or equal to -4. Thus, this would be signified by a closed point at -4 and an arrow pointing in the negative direction, in this case to the left. (The closed point is not something to worry about in this specific question, however, in the future, a closed point signifies less/greater than + equal to, while an open one just signifies less/greater than).
This means that our answer is B.
Hope this helps!
