Solution:
The given inequalities are \[x-2y\le 3\], \[3x+4y\ge 12\], \[x\ge 0\], \[y\ge 1\]
For \[x-2y\le 3\]
Let us put value of \[x=0\] and \[y=0\] in equation one by one, we get
\[y=-1.5\]and \[x=3\]
We get the required points as \[(0,-1.5)\]and \[(3,0)\]
To check if the origin is included in the line`s graph \[(0,0)\]
\[0\le 3\], which is true and hence the solution area would be on the left of the line`s graph
For \[3x+4y\ge 12\],
Let us put value of \[x=0\] and \[y=0\] in equation one by one, we get
\[y=3\]and \[x=4\]
We get the required points as \[(0,3)\]and \[(0,4)\]
To check if the origin is included in the line`s graph \[(0,0)\]
\[0\ge 12\], which is not true
Therefore, the solution area would of include the origin and the required solution area would be on the right side of the line`s graph.
For \[x\ge 0\],
We can say that all the values of y, the value of x would be same in the given inequality, which would be the region above the x axis on the graph.
For \[y\ge 1\]
We can say that for all the values of x, the value of y would be same in the given inequality.
As \[y\ge 1\],the origin is not included
Therefore, the solution area would be on the left side of the line`s graph.
In the below graph the shaded area in the graph is the required solution of the given inequalities
