The boundary line is solid because the inequality includes equality. Since x can be less than or equal to -2, the points on the line are part of the solution set.
Conditions: The inequality is non-strict (≤).; The boundary line is .

The boundary line is dashed because the inequality is strict. Since x is greater than 3 but not equal to 3, the points on the line are excluded from the solution set.
Conditions: The inequality is strict (>).; The boundary line is .
