Question

For the following inequality, indicate whether the boundary line should be dashed or solid.

Answer 1

So the problem ask to determine if the said inequality indicates where its boundary line should be dashed or solid but first you must consider that the solid should be used if the line is part of the solution and the dashed designates that the line is not part of the solution. Base on that, the answer would be SOLID. I hope you are satisfied with my answer 

Answer 2

Hey! a dotted line is used for < and > while a solid one is used for ≤ and ≥
So in this case its... Solid :D
