Answer:
Solid
Step-by-step explanation:
Rewriting for the sake of clarity:
1) For the following inequality, indicate whether the boundary line should be dashed or solid. x ≤ 5
2) Since it is a closed interval which includes the number 5 then this can also be written as:
[tex](-\infty,5][/tex]
3) Hence, we can graph it as a solid line crossing the point (5,0). For the x coordinate 5, is within the interval.
