CHAPTER 4 : Linear
equations in two variables |
TOPIC:-
Chapter:- 4 : Linear equations in two variables
DURATION:-
This lesson is divided into
seven modules and it is completed in fourteen class meetings.
PRE- REQUISITE KNOWLEDGE:-
- Knowledge of linear equations in one variable.
- Knowledge of Cartesian coordinate system.
- Knowledge of representing the points in the coordinate system.
TEACHING AIDS:-
Green Board, Chalk, Duster, Charts, smart board, projector and
laptop etc.
METHODOLOGY:-
Demonstration and
Lecture method
OBJECTIVES:-
- Recall of linear equations in one variable.
- Introduction to the equation in two variables.
- Focus on the linear equation of the type ax + by + c = 0.
- Explain that a linear equation in two variables has infinitely many solutions.
- Justify the above point by finding different ordered pairs and plotting then and showing that they lie on a line.
- Graph of linear equations in two variables.
- Examples, problems from real life, including problems on ratio and proportion.
- Algebraic and graphical solutions of linear equations in two variables.
- Method of finding equation parallel to the x- axis or parallel to y- axis.
PROCEDURE :-
Teacher will ask the
class about the meaning of word ‘Linear equations in one variable’ and
Cartesian coordinate system.
After getting the different answers from the class, Teacher himself explains the meanings , definition and explanations step by step as follows.

An equation with one variable and with degree one is called linear equation in one variable. For example : ax + b = 0, x + 3 = 0, 5y – 10 = 0
|

2 |
An equation with two variables and with degree of each variable = 1 is called linear equation in two variables. Example 4x + 3y = 0 General linear equation in two variable is ax + by + c = 0, Here a is the coefficient of x, b is the coefficient of y and c is the constant term.

Graph of linear equation in two variable is a straight line and on a straight line there are infinitely many points. Each point on the straight line is the solution of that equation. So linear equation in two variable has infinitely many solutions. More over in a linear equation in two variable for every value of x we get unique value of y and vice-versa. Hence linear equation in two variables has infinitely many solutions.

i) Let us take an example of equation 3x + 4y = 12 ii) From this equation either find the value of x or y iii) Take only those values of y with which 3 can be cancelled If y = 0, then x = 4 If y = 3, then x = 0 If y = - 3, then x = 8 If y = 6, then x = - 4 and so on iv) Write these points in a box
Similarly we can find infinitely many solution of the equation

Let us take an equation of line 2x + 5y = 8 We want to check whether point (2, -2) lie on this line or not. In the above equation putting x = 2 and y = -2 we get 2 x 2 + 5 x -2 = 8 4 - 10 = 8 - 6 ≠ 8 LHS ≠ RHS Point (2, -2) does not lie on the given line If we get the result LHS = RHS then the given point lie on the given line.

Let us take a line 3x + 4y = 12, whose graph is to be made. First of all find at least three points on the line according to the method explained in point 4 Now plot these point in the Cartesian plane. Join all these points with the help of scale so that the line which touches all the points is become a straight line. |

Let us suppose an example 5x-10=0 5x =10 ⇒ x = 2 In one variable : x = 2 simply represented on a straight line. In two variables : x = 2 is a line parallel to y-axis Similarly y = 3 is a line parallel to x - axis

EXPECTED OUTCOMES:-
- After studying this lesson students will be able to understand the concept of linear equation in one variable and linear equation in two variables.
- Students should know the method of finding the points on the number line and able to draw its graph.
- Students also know the representation of the number line in one variable and in two variables
STUDENTS DELIVERABLES:-
Review questions assigned by the teacher.
Solve
NCERT problems with examples and some extra questions from the refreshers.
Students can prepare a project report or PPT on the basic concepts of pair of linear equations in two variables
EXTENDED LEARNING:-
Students can extend their learning by studying basic concepts and formulas of mathematics through the Resource Centre Mathematics and can find interesting topics on mathematics at the site https://www.cbsemathematics.com/
ASSESSMENT TECHNIQUES:-
At the end of the lesson a Class Test will be taken.
Re-test(s) will be conducted on the basis of the performance of the students in the test.
Worksheets and assignments should be given to the students.
Arrangement should be made for the oral test or quiz competitions.
