Question

"Question 1 Which one of the following options is true, and why? y = 3x + 5 has (i) a unique solution, (ii) only two solutions, (iii) infinitely many solutions

Class 9 - Math - Linear Equations in Two Variables Page 70"

Answer 1

Hi friend !

A linear equation in two variables has infinitely many solutions!
This is because , as we put any value for x , we automatically get the corresponding value of "y'. So like this we can find many values of "x" and "y" satisfying the equation

Answer 2

Any pair of values of x and y which satisfy the given equation in x & y is called its solution. This solution is written as an ordered pair(x,y).

 

A linear equation in two variables has infinitely many solutions.

 

 -------------------------------------------------------------------------------------------------

Solution:

We know that a linear equation in two variables has infinitely many solutions.

Here, given equation is a linear equation in two variables x and y so it has infinitely many solutions.

option iii is correct
