Question
From the choices given below, choose the equation whose graph is given in fig. below.
(i) y = x + 2 (ii) y = x – 2 (iii) y = −x + 2 (iv) x + 2y = 6
[Hint: Clearly, (2, 0) and (−1, 3) satisfy the equation y = −x + 2]
Solution
Clearly ( 2, 0 ) and (-1 , 3 ) satisfy the equation y = -x + 2
∴ The equation whose graph is given by y = - x + 2
