In this video, we cover section 13.2 Solution of a Linear Equation in Two Variables of Chapter 13 "Two Variables, One Line" (Ganita Manjari Part 2, Class 9 NCERT new syllabus), with all the examples solved step by step with graphs.
📌 What you will learn:
✔ What is a solution? Ordered pairs (x, y)
✔ Why a linear equation in two variables has infinitely many solutions
✔ Every solution is a point on the graph: the graph is a straight line
✔ Quick graph trick: put x = 0 and y = 0
📝 Examples solved:
Example 2 – Two solutions of 2x + y = 7, its graph, and 4 more solutions from the graph
Example 3 – Graphs of 4x + 3y = 12 and 2x + 5y = 0
Example 4 – (−3, 4) is a solution of both equations: find a and b
Think and Reflect – When c = 0, the line always passes through the origin
