CLASS-10 CHAPTER-3 PAIR OF LINEAR EQUATIONS IN TWO VARIABLES
EXERCISE -3.2 QUE-4📚🤗

BASED ON SOLUTIONS OF LINEAR EQUATIONS

Method of Solution of a Pair of Linear Equations in Two Variables. Coordinate of the point (x, y) which satisfy the system of pair of linear equations in two variables is the required solution. This is the point where the two lines representing the two equations intersect each other.


All about Lines


Nature of 2 straight lines in a plane

They intersect at exactly one point pair of linear equations which intersect at a single point.

ii) They are parallel

iii) They are coincident


Graphical method of finding solution of a pair of Linear Equations

Graphical Method  of finding the solution to a pair of linear equations is as follows:

Plot both the equations (two straight lines)

Find the point of intersection of the lines.

The point of intersection is the solution.
