Question

From the choices given below, choose the equation whose graphs are given in Fig.  and Fig. .

Answer 1

Solution for graph of linear equation of Fig. :

Sum of (x + y) = 0. 

Equation for this is 

(ii) x + y = 0 because x = -y we have OR -x = y 

0 = 0 

1 = -1 

-1 = 1 

Solutions for graph for linear equation in Fig. :

x + y = 2 is common in all. 

∴ y = -x + 2 

∴ (iii) y = -x + 2 equation.
