which number line shows the solution to x < -3

Hi there!
Answer:
I think the answer is A.
Step-by-step explanation:
An inequality is a statement that compares mathematical expressions that are not equal. The expressions are separated by an inequality symbol (<,>,≤,≥, or ≠).
A variable is a letter or symbol used to represent an unknown quantity.
The arrow points to the left.
The circle is open.
If it's greater/less than or equal to it should be closed.
Hope this helps!
