The graph shown represents an inequality. the solid line that forms the boundary tells you that the graph is correct. the inequality is correct. the inequality has no equal sign in it. the inequality has an equal sign in it.

D. The inequality has an equal sign it

Step-by-step explanation:

We use solid lines whenever the inequality contains or . That means it contains an equal sign which means the boundary line is inclusive.

On the other hand when the inequality does not have an equal sign in it we use a dashed line to indicate that all values on the boundary line are not inclusive.

That is we use a dashed or broken line for the boundary line of an inequality whenever it contains .

The correct answer is D
