Graphing a linear inequality with test points

The video tutorial explains how to graph inequalities with two variables by treating them like equations. It covers graphing in slope-intercept form, identifying the Y-intercept and slope, and plotting points. The tutorial also discusses using dotted lines for inequalities and choosing test points, emphasizing the use of (0,0) unless the line passes through it. Finally, it explains how to determine which side of the graph to shade based on true statements.
