The video tutorial explains how to graph absolute value inequalities by first graphing the corresponding equation and determining the solution set. It covers identifying the inequality symbol to decide if the line is solid or dashed, understanding transformations to shift the graph, and the effects of negative and fractional coefficients. The tutorial also demonstrates creating a table of values to plot points and using symmetry to complete the graph. Finally, it explains how to determine which side of the graph to shade based on test points.
