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.
