Replace the inequality signs by equality signs and plot the two equations.
Now, check whether (0, 0) satisfies the inequalities.
If origin satisfies the inequality then the region containing
origin is the region for inequality or vice-versa.
As 0>-1, so y>4x-1 its true for (0,0).
Again, for x=0:
As 0<3, so y<4x-1 is true for (0,0)
Plot the region of inequality and the region satisfying both the
inequalities is the feasible region. The shaded region is the feasible
