Plot the points (3, 5) and (− 1, 3) on a graph paper and verify that the straight line passing
through these points also passes through the point (1, 4).
From the choices given below, choose the equation whose graph is given in Fig. below.
(i) y = x (ii) x + y = 0 (iii) y = 2x (iv) 2 + 3y = 7x
[Hint: Clearly, (-1, 1) and (1, -1) satisfy the equation x + y = 0]
