Описание: Class 9 Math – Exercise 5.1 Question 3 (Linear Inequalities in Two Variables) | Full Solution | English Medium | New Book 2025

Welcome to this detailed lecture on Exercise 5.1 Question 3 from Class 9 Mathematics (Unit 5: Linear Equations and Inequalities) as per the Punjab Textbook New Syllabus 2025.

In this video, we will:
✅ Learn how to shade the solution region for linear inequalities in the xy-plane
✅ Understand the concept of boundary lines (equalities) and shaded regions (inequalities)
✅ Identify which side of the line satisfies the inequality using test points
✅ Draw neat and accurate graphs for inequalities such as:

2x + y ≤ 6

3x + 7y ≥ 21

3x – 2y ≥ 6

5x – 4y ≤ 20
and more!


This video is perfect for students who want to visualize and clearly understand how to represent linear inequalities graphically.
