How do you determine if a point is a solution to a linear inequality?

Back

To determine if a point is a solution, substitute the x and y values of the point into the inequality. If the inequality holds true, the point is a solution.

How do you graph a linear inequality?

Back

1. Graph the corresponding linear equation as a solid or dotted line. 2. Choose a test point not on the line to determine which side of the line to shade.

What is a test point in graphing inequalities?

Back

A test point is a point used to determine which side of the line to shade. A common choice is the origin (0,0), unless it lies on the line.
