The graph shows an open circle at -6 and the shading extending to the right, indicating that the variable $a$ is greater than -6.

Thus, the correct inequality is:

A) $a > -6$

If you'd like further details or explanations, feel free to ask!

Here are 5 related questions:

1. How do you interpret a closed circle versus an open circle on a number line?
2. What does shading to the left of a number on a number line mean in terms of inequalities?
3. Can you explain how to write inequalities from graphs that have closed circles?
4. What is the difference between $a \geq -6$ and $a > -6$?
5. How would you graph the inequality $a > -6$?

Tip: Always remember that an open circle represents "not including" the number, and a closed circle means "including" the number!
