From the choices given below, choose the equation whose graphs are given in fig (4.6) and fig (4.7).

**For Fig. 4. 6 For Fig. 4.7**

**(i)** **(i)**

**(ii)** **(ii)**

**(iii)** ** (iii)**

**(iv)** ** (iv)**

** Fig 4.6 Fig 4.7**

**Answer:**

In **fig 4.6**, we can see that points , and lie on the line.

Out of the four given choices, is the only line which passes through points , and . Therefore, in **fig 4.6**, equation of the line is .

In **fig 4.7**, we can see that points , and lie on the line.

Out of the four given choices, is the only line which passes through points , and . Therefore, in **fig 4.7**, equation of the line is .
