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

**Solution:**

(i) We can write the equation in one variable as,

x = -$\frac{9}{2}$

And the geometric representation will be,

(ii) We can write the equation in two variable as,

2x + 0y + 9 = 0

It is represented as a line parallel to Y-axis.
