Draw the graph of the equation ( x + y = 4 ).

While Exercise 4A introduces the basic concepts, focuses on the graphical representation of these equations. This is where many students face challenges, as it transitions from theoretical algebra to visual geometry. rs aggarwal maths class 9 4b

Introduction

with a straight line. Extend it across the graph. Draw the graph of the equation ( x + y = 4 )

| Concept | Explanation | | :--- | :--- | | | A linear equation in two variables has infinitely many solutions. You only need 2–3 to draw the line. | | Graph is a Straight Line | Unlike quadratic equations, the graph here is always a straight line. | | Intercepts | The easiest points to find are the x-intercept (put ( y = 0 )) and y-intercept (put ( x = 0 )). | Step-by-Step Solution Approach (Example) Let’s solve a typical problem from RS Aggarwal Class 9 4B: Introduction with a straight line

Keep practicing, keep plotting, and soon you'll be solving these problems in minutes.
