We have the following compound inequality:
[tex] -5<a-6<2 [/tex]
So, we need to find the solution to this problem. In this way, for property of inequality by adding 6 to each side we have:
[tex] \mathbf{6}-5<a-6+\mathbf{6}<2+\mathbf{6} \\ \\ \boxed{1<a<8} [/tex]
This inequality does not include neither the number 1 nor the number 8. So, the circle in these values must be empty. Therefore, the graph that matches this result is the second one.
