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]

Answer 1

Clearly ( 2, 0 ) and   (-1 , 3 ) satisfy the equation  y = -x + 2

∴ The equation whose graph is given by  y = - x + 2
