What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables. The solution is the set of all points that satisfy all inequalities in the system.

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

Back

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

What does the symbol '≤' mean in an inequality?

Back

'≤' means 'less than or equal to'. It indicates that the value on the left can be less than or equal to the value on the right.

What is the graphical representation of an inequality?

Back

The graphical representation of an inequality is a shaded region on a graph, indicating all the possible solutions that satisfy the inequality.

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 (for '≤' or '≥'), while a dashed line indicates that points on the line are not included (for '<' or '>').

What does it mean for a point to be a solution to a system of inequalities?

Back

A point is a solution to a system of inequalities if it lies in the overlapping shaded region of the graphs of all inequalities in the system.

How do you solve a system of inequalities by graphing?

Back

To solve by graphing, graph each inequality on the same coordinate plane, shade the appropriate regions, and identify the overlapping area as the solution.

What is the solution set of a system of inequalities?

Back

The solution set is the collection of all points that satisfy all inequalities in the system, represented graphically as a shaded region.
