Answer» e correct ANSWER is (c)/side of a square.The correct graph is the figure attached.How to DRAW the graph :- we know , for a < 0 , |a| = - aFor X, y > 0.we draw :- x + y = 4.For, x < 0 , y > 0 We draw :- - x + y. = 4.For , x < 0 , y < 0we draw :- - x - y = 4.For , x >0 , y < 0.we draw :- x - y = 4.The four lines intersect at ( 4,0) , (0,4) , (-4, 0) , ( 0 , -4) and the RESULTANT figure is a square. |
