"Question 1 Give the geometric representation of y = 3 as an equation (I) in one variable (II) in two variables
Class 9 - Math - Linear Equations in Two Variables Page 77"
Answers
Given, linear equation is y=3
i)
If Y = 3 is treated as an equation in one variable, then it has a unique solution y= 3. So it is a point on the number line.

ii)
Given equation Y equal to 3 can be written as 0.x + y = 3, which is a linear equation in two variables x and y.
This is represented by a .Here all the values of X are permissible because 0.x is always 0. However, y must satisfy the equation y=3.

Thus, the graph AB is a line parallel to X-axis at a distance of 3 units in the positive direction of Y axis.
