Answer:
Option 1.
Step-by-step explanation:
If the inequality contains the signs < or > then the number line should have an open dot (the dot is not colored in). If the inequality contains the signs ≥ or ≤ then the number line should have a closed dot (the dot is colored in).
Since the sign is < you should pick the number line with the open dot that has an arrow facing the left side instead of the right, which is option 1.
I hope this helps you, have a nice day.
