Give the geometric representations of as an equation:

**(i)** in one variable

**(ii)** in two variables

**Solution (i)**

Geometrical representation of as an equation in one variable is just a point shown on the number line.

**Solution (ii)**

Equation can be written as () as two variables equation.

We can represent this two variables equation on Cartesian place. This equation would be shown as line parallel to y-axis.

Let's write 3 set of points which lie on equation .

Points and lie on the line .

When we plot these points, we get a line parallel to y-axis.
