The line passing through the points
and
is
.
Consider the points
and
.
The line equation is
.




Observe the figure:
\The shaded region in the figure is below the line, hence the inequality is
.
Consider the points
and
.
The line equation is
.




Observe the figure:
\The shaded region in the figure shaded region is left to the line, hence the inequality is
.
Consider the points
and
.
The line equation is
.




Observe the figure:
\The shaded region in the figure is above the line, hence the inequality is
.
Consider the points
and
.
The line equation is
.




Observe the figure:
\The shaded region in the figure is right to the line, hence the inequality is
.
Therefore,the constraints are
\
