Q-1 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 x-axis at a distance of units above it.
