**1. Give the geometric representations of y = 3 as an equation**(i) in one variable

(ii) in two variables

**Answer**

**(i) in one variable, it is represented as**y = 3

**(ii) in two variables, it is represented as a line parallel to X-axis.0x + y = 3**

**2. Give the geometric representations of 2x + 9 = 0 as an equation**(i) in one variable

(ii) in two variables

**Answer**

**(i) in one variable, it is represented as**x = -9/2

**(ii) in two variables, it is represented as a line parallel to Y-axis.2x + 0y + 9 = 0**
