What is a linear inequality?

Back

A linear inequality is a mathematical statement that compares a linear expression to a value using inequality symbols (>, <, ≥, ≤).

What does the solution of a linear inequality represent?

Back

The solution of a linear inequality represents all the points (x, y) that satisfy the inequality, often visualized as a region on a graph.

How do you graph a linear inequality?

Back

1. Graph the corresponding linear equation as a solid line (for ≤ or ≥) or a dashed line (for < or >). 2. Shade the region that satisfies 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 (≥ or ≤), while a dashed line indicates that points on the line are not included (> or <).

What does the intersection of two inequalities represent?

Back

The intersection of two inequalities represents the set of points that satisfy both inequalities simultaneously.

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

Back

Substitute the coordinates of the point into each inequality. If the point satisfies all inequalities, it is a solution.

What is the graphical representation of the inequality y < 2x - 1?

Back

The graph will have a dashed line for y = 2x - 1, and the region below the line will be shaded.

What does the inequality y ≥ -2x + 3 represent graphically?

Back

It represents a solid line for y = -2x + 3, with the region above the line shaded.

What is a feasible region in the context of linear inequalities?

Back

A feasible region is the area on a graph where all constraints (inequalities) are satisfied, representing all possible solutions.

How do you find the vertices of a feasible region?

Back

Vertices can be found by identifying the points of intersection of the boundary lines of the inequalities.
