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 can you graph a system of inequalities?

Back

Graph each inequality on the same coordinate plane, shading the region that satisfies each inequality.

What is the significance of the boundary line in an inequality?

Back

The boundary line represents the points where the inequality changes from true to false. If the inequality is strict (>, <), the line is dashed; if it includes equality (≥, ≤), the line is solid.

What does the notation y > 2x - 4 represent?

Back

It represents the region above the line y = 2x - 4, where y is greater than the value of 2x - 4.

How do you determine if a point is a solution to the inequality y < 2?

Back

Substitute the x-value of the point into the inequality. If the resulting y-value is less than 2, then the point is a solution.

What is the meaning of the inequality x + y ≤ 300 in a real-world context?

Back

It represents a constraint where the total number of adults (x) and children (y) cannot exceed 300 seats.
