GCSE Secondary Maths Age 13-17 - Algebra: Inequalities - Explained

The video tutorial explains how to graph straight lines and shade regions to represent inequalities. It covers plotting the lines X + Y = 7, Y = 2X, and Y = 3, and discusses how to determine which regions to shade based on the inequalities. The tutorial emphasizes understanding the relationship between the line and the regions above and below it, providing tips for correctly shading the required areas. The goal is to help students solve graphing inequality problems effectively.

What is the significance of shading in the context of graphing inequalities?

Explain how to determine the region that satisfies the inequality X + Y < 7 on a graph.

Describe the process of plotting the line for the equation Y = 2X.

What does it mean when a line on a graph represents Y = 3?

How can you visually identify the region where Y is greater than 3 on a graph?
