I would agree with both of you. The student should not box in the solution set creating the solid line

I believe you were correct. To make a solid edge implies that the boundary is in the solution when it is not  in fact I warned my group before we started that if a student chose a point on the dotted line to be a point in the solution set that it was incorrect. (And we had at least one that did.)
