Answer -
(i) 
It can be observed that x = 0, y = 4and x = 4, y = 0 are solutions of the aboveequation. Therefore, the solution table is as follows.
The graph of this equation is constructed as follows.
(ii) 
It can be observed that x = 4, y = 2and x = 2, y = 0 are solutions of the aboveequation. Therefore, the solution table is as follows.
The graph of the above equation is constructed as follows.
(iii) y = 3x
It can be observed that x = −1, y =−3 and x = 1, y = 3 are solutions of theabove equation. Therefore, the solution table is as follows.
The graph of the above equation is constructed as follows.
(iv) 3 = 2x + y
It can be observed that x = 0, y = 3and x = 1, y = 1 are solutions of the aboveequation. Therefore, the solution table is as follows.
The graph of this equation is constructed as follows.
