Transcript

Ex 6.2, 1 Solve the following inequalities graphically in two-dimensional plane: x + y < 5 x + y < 5 Lets first draw graph of x + y = 5 Drawing graph Checking for (0,0) Putting x = 0, y = 0 x + y < 5 0 + 0 < 5 0 < 5 which is true Hence origin lies in plane x + y < 5 . So, we shade left side of line
