Question

draw the graph for linear equation x+y=0 check(2,2)is the solution are not

Answer 1

the graph will be a straight line passes through origin making 45° with negative x axis
and (2,2) is not the solution
first we can write x=-y
now put y=1,2,3,0 or you want to put
and we get the value of x like x=-1;-2,-3,0
place these point on graph and join them
