How do you graph a linear inequality?

Back

To graph a linear inequality, first graph the corresponding linear equation as a dashed line (for < or >) or a solid line (for ≤ or ≥). Then shade the region that satisfies the inequality.

What does the solution of a system of linear inequalities represent?

Back

The solution of a system of linear inequalities represents all the points (x, y) that satisfy all inequalities in the system, typically shown as a shaded region on a graph.

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

Back

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

What is the significance of the intersection of shaded regions in a graph of inequalities?

Back

The intersection of shaded regions represents the set of solutions that satisfy all inequalities in the system.
