Question

Solve the following inequalities graphically in two-dimensional plane:

1. x + y < 2

Answer 1

Answer

y<−2  is the shaded region shown in the graph.

If we put O(0,0) in the LHS,we get LHS=0

Now LHS>−2

 Means O(0,0) lies on opposite side of "less than " side of  the line.

Hence required region is "non-origin" side of the line.

Answer 2

Answer:

above answer is correct hope it helps you
