Answer:
The third graph is correct
Step-by-step explanation:
Hiiii,
Since the sign is < and doesn't have a line underneath (or equal to), it means we have an open circle. We also know that the line has to go to the left because all the values that go to the left make the inequality true.

Hope this helps :)
