# From the choices given below, choose the equation whose graphs are given in Fig. 4.6 and Fig. 4.7.

**Solution:**

- Points on the given line are (-1, 1), (0, 0), and (1, -1).
- It can be observed that the coordinates of the points of the graph satisfy the equation x + y = 0.

Therefore, x + y = 0 is the equation corresponding to the graph as shown in the first figure.

Hence, (ii) is the correct answer.

- Points on the given line are (-1, 3), (0, 2), and (2, 0).
- It can be observed that the coordinates of the points of the graph satisfy the equation y = -x + 2.

Therefore, y = - x + 2 is the equation corresponding to the graph shown in the second figure.

Hence, (iii) is the correct answer.
