Exploring Writing Inequalities

The video tutorial covers writing and graphing inequalities, starting with basic concepts and progressing to compound inequalities and graphing linear inequalities with shading. It demonstrates how to graph inequalities on a number line, translate sentences into inequalities, and verify solutions. Key symbols such as less than, greater than, and equal to are reviewed.
