Question

what type of line is used with the following symbols, ≤ and ≥? dashed or dotted solid

Explanation:

In graphing inequalities, the symbols $\leq$ and $\geq$ indicate that the values on the boundary line are included in the solution set, so a solid line is used to represent this. Dashed/dotted lines are reserved for strict inequalities ($<$ and $>$) where boundary values are excluded.

Answer:

solid
