Graphs of Linear Inequalities

Front

What is a linear inequality?

Back

A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols such as <, >, ≤, or ≥.

What does the symbol '≤' indicate when graphing?

Back

The symbol '≤' indicates that the line is included in the solution set, so a solid line is used when graphing.

What does the symbol '>' indicate when graphing?

Back

The symbol '>' indicates that the line is not included in the solution set, so a broken (dashed) line is used when graphing.

What is the difference between a solid line and a dashed line in graphing inequalities?

Back

A solid line indicates that points on the line are included in the solution (≤ or ≥), while a dashed line indicates that points on the line are not included ( < or >).

How do you determine which side of the line to shade when graphing an inequality?

Back

Choose a test point not on the line (commonly (0,0)). Substitute it into the inequality. If the inequality holds true, shade the side of the line that includes the test point.
