Algebra 1 - Graphing an inequality with test points - Cool Math

The video tutorial explains how to graph inequalities, focusing on the common pattern where the graph follows the direction of the inequality sign. However, this pattern does not apply when the variable is on the right side of the inequality. The tutorial emphasizes the importance of testing points to determine if they are true or false, and shading the graph accordingly. It also warns against relying on shortcuts, especially when the variable is on the right or negative, and stresses the need for careful analysis.

What is the significance of picking points like -1, 1, and 3 when graphing inequalities?

Discuss the importance of being careful with the placement of the variable in inequalities.
