Answer :

In this question, we will apply the concept of a common solution area to find the signs of inequality by using their given equations and the given common solution area(shaded part).


If a line is in the form ax+by = c and c is positive constant(in case of negative c the rule becomes opposite), so there will be two cases to discuss, which are,


If a line is above origin :–


(i). If the shaded area is below the line then ax+by<c


(ii). If the shaded area is above the line then ax+by>c


If a line is below origin then the rule becomes opposite.


According to the rules the answer will be,
