Answer:
Step-by-step explanation:
If it's less than or greater than (<, >), then the circle is hollow.
If it's less than or equal to, or greater than or equal to (≤, ≥), then the circle is solid.
Less than points to the left, greater than points to the right.
Here we have less than (not equal to). So the circle is hollow, and the arrow points left. So the correct answer is the first one.
We can check our answer by picking a point and seeing if it's true. If we pick c=-6, is it true that -6 < -1? Yes.
