The fact that the line is dashed means that the inequality being graphed does not include "equals"

You have a graph of



as opposed to a graph of



which graph would be identical except that the boundary line would be solid.

The dashed line means that points that are actually ON the line are NOT included in the solution set of the inequality. Three of the listed points are actually on the line, and only one of them is properly into the shaded area.
