Join this Mission Mid Terms series to revise all the important concepts in your NCERT Class 9 Maths Chapter 4. Linear Equations in Two Variables.

In this online class, your BYJU’S educator, Khushbu Ma’am, covers the following topics in detail:
1. Linear Equations in 2 Variables
2. Graphical Representation
3. Forming Equations
4. General Form of Linear Equation

A linear equation in two variables has infinitely many solutions. The graph of every linear equation in two variables is a straight line. Every point on the graph of a linear equation in two variables is a solution to the linear equation. Moreover, every solution of the linear equation is a point on the graph of the linear equation. Join this class to learn more about Linear Equations in Two Variables.

*H/W Solution:*

As y = 4x
=> y - 4x = 0
=> -4x + y = 0
=> (-4)x + (1)y + (0) = 0
Therefore, a = -4 ; b = 1 ; c = 0

*Answer:* (a) -4, 1, 0

Mam i have a small doubt that
Should I buy Rd Sharma or oswaal or rs Agarwal for maths class 9 mam pls reply

[radharadha]

Mam please tell me this question
Draw the graphs of the lines X-y =1and 2x+y=8. shade the area formed by these two lines and the y-axis.Also, find this area.

[sunilbhosale]

Thank you Ma'am for such videos and sessions it helped a lot at exam times 🥰THANK YOU SO MUCH MAM 🥰

[damngamingt]

Hello ma'am
Fabulous explaination
I am loving because of byjus and a teacher like you🤩🤩🤩

[aradhayasingh]

Hello Mam the secession was amazing, I have my test of the same chapter on this Wednesday would you please make a separate video on graphs of Linear Equation and a short revision quiz

[bluebluebulbs]

Everyone: listening to the class
Me: enjoying her nails

[prempremyadav]

The session was really really amazing 💜☺️

[jiyabhatt]

Thank you ma'am i understand everything you the best 💖👍👍💗

ONCE AGAIN THANK YOU FOR YOUR EFFORTS

[besties]

The answer is
Option a
-4, 1, 0
By Neetha

[niverthimurthy]

Mam, make a session on important questions of ax+by+c=0 and y=mx mamm

[shreeseshan]

H. W answer:if y =4x in the form ax+by+c=0
Then=-4x+y+0=0
So the option A is right!
The session was lovely mam got crystal clear in concept! 🤓

[aradhayasingh]

HW Questions Answer first given by me -( Option D -4, 1, 0 )

[Ayushpro]

Home work and is b
4x+1y-0=0
5 - 0 = 0

[anitharajgattu]

Am very easy to learn by ur classes..and when you make a new video on maths new lesson mam..

[triomelon]

Ma'am u said 5, 0for y axis but its 0, 5
