What is a linear inequality?

Back

A linear inequality is an inequality that involves a linear function, typically expressed in the form ax + by < c, ax + by > c, ax + by ≤ c, or ax + by ≥ c.

How do you represent a solution to a system of linear inequalities graphically?

Back

A solution to a system of linear inequalities is represented graphically by the region where the shaded areas of the inequalities overlap.

How do you determine if a point is a solution to a system of inequalities?

Back

To determine if a point is a solution to a system of inequalities, substitute the point's coordinates into each inequality. If the point satisfies all inequalities, it is a solution.
