What is a linear inequality?

Back

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

What does the symbol '≥' indicate in a linear inequality?

Back

The symbol '≥' indicates that the value on the left side of the inequality is greater than or equal to the value on the right side.

What does the symbol '≤' indicate in a linear inequality?

Back

The symbol '≤' indicates that the value on the left side of the inequality is less than or equal to the value on the right side.

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

Back

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

What is a system of linear inequalities?

Back

A system of linear inequalities consists of two or more linear inequalities that are considered simultaneously.

Front

How do you determine the solution set of a system of linear inequalities?

Back

The solution set is the region where the shaded areas of all inequalities overlap on the graph.

What does it mean if a point lies on the boundary line of an inequality?

Back

If a point lies on the boundary line of an inequality, it is included in the solution set if the inequality is ≤ or ≥, but not included if the inequality is < or >.

Graph both inequalities, using a solid line for the first and a dashed line for the second. The solution is the region where the shaded areas overlap.
