Q1 Give the geometric representation of as an equation

In one variable

In two variables
Solution:

In one variable

The given equation is

In one variable

The representation of on the number line is shown below:


In two variables
therefore
It is linear equation in two variable and . This is represented by a line. All the value of are permissible because is always .However, must satisfy the relation .hence,two solutions of the given equation are s
Thus the graph AB is a line parallel to the xaxis at a distance of units above it.
