Plotting Inequalities on Number Lines

The video tutorial explains how to plot inequalities on number lines, providing a visual representation of the values a variable can take. It covers the use of open and closed circles to denote whether a number is included in the inequality. Examples include plotting x > 3, x ≥ 3, x < 8, x ≤ 8, and inequalities involving negative numbers. The tutorial also addresses combined inequalities, demonstrating how to represent them on number lines. The video concludes with a summary of the key concepts and encourages practice through assessments.
