We can write an equation for the number line. The open circle means < or >. Since the open circle is at 0, that means c is going to be less than 0. The equation will look like this:
c < 0
The lines goes to left and since their is an arrow at the end of it, it never ends. This means that all negative numbers are solutions to the inequality. This means that -13 will be a solution to the inequality. It also satisfies the inequality we wrote above:
-13 < 0 (-13 is less than 0)
Therefore, the answer is [ True ]
Best of Luck!
