How can you determine if a point is part of the solution set for a linear inequality?

Back

Substitute the point into the inequality; if it satisfies the inequality, it is part of the solution set.

Front

What does the inequality symbol '>' indicate about the boundary line?

Back

The boundary line is not included in the solution set (dashed line).

Front

What does the inequality symbol '≥' indicate about the boundary line?

Back

The boundary line is included in the solution set (solid line).
