Answer
See below:
Work Step by Step
Step I:
In the given above expressions, replace inequalities with equality, and draw it:
\[\begin{align}
& 2x-y=4; \\
& \text{And, }2x-y=-1
\end{align}\]
In the first equation,
\[\begin{align}
& x-\text{intercept}=2 \\
& y-\text{intercept}=-4 \\
\end{align}\]
In the second equation,
\[\begin{align}
& x-\text{intercept}=-\frac{1}{2} \\
& y-\text{intercept}=1 \\
\end{align}\]
Step II:
Put\[x=0,\text{ and }y=0\], in the inequalities equations.
In the first inequality:
\[0\le 4\]; it is true.
In the second inequality:
\[0>-1\]; it is also true.
Therefore, both the inequalities contain the origin.
Graph does not include the line 2x – y = -1 but it includes 2x – y = 4
