Question
From the choices given below, choose the equation whose graphs are given in Fig. (1) and Fig. (2).
For Fig. 1 For Fig. 2
(i) y = x (i) y = x + 2
(ii) x + y = 0 (ii) y = x – 2
(iii) y = 2x (iii) y = – x + 2
(iv) 2 + 3y = 7x (iv) x + 2y = 6

Fig. 2
Solution
For Fig. (1). The correct equation is
(ii) x + y = 0.
For Fig. (2). The correct equation is
(iii) y = – x + 2.
