Solve the given inequalities $x-2 y \leq 2, x+y \geq 3,-2 x+y \leq 4, x \geq 0, y \geq 0 g r a p h i c a l l y$ in two - dimensional plane.
The graphical representation of $x-2 y \leq 2, x+y \geq 3, y \geq 0$
$-2 x+y \leq 4, x \geq 0$ is given by common region in the figure below.
$x-2 y \leq 2 \ldots \ldots$ (1)
$x+y \geq 3 \ldots \ldots$ (2)
$x \geq 0 \ldots \ldots$ (3)
$y \geq 0 \ldots \ldots$ (4)
$-2 x+y \leq 4 \ldots \ldots \ldots$ (5)
Inequality (1) represents the region above line $x-2 y=2$ (including the line $x-2 y=2$ ).
Inequality (2) represents the region above line $x+y=3$ (including the line $x+y=3$ ).
Inequality (3) represents the region in front of line $x=0$ (including the line $x=0$ ).
Inequality (4) represents the region above line $y=0$ (including the line $y=0$ ).
Inequality (5) represents the region below line $-2 x+y=4$ (including the line $-2 x+y=4$ ).
Therefore,every point in the common shaded region including the points on the respective lines represents the solution for the given inequalities.
This can be represented as follows,
