Option D: Graph C is the solution to the system of linear inequalities.
Explanation:
The system of linear inequalities are and
Let us graph the inequality
Let us substitute the coordinate in the inequality
, we get,
This is false. Hence, the solution does not contain the coordinate
Thus, let us shade the upper part of the line in the graph.
Similarly, let us substitute the coordinate in the inequality
, we get,
This is false. Hence, the solution does not contain the coordinate
Thus, let us shade the lower part of the line in the graph.
The solution to the system of linear inequality is the intersection of the two regions.
Thus, the solution of the inequality is Graph C.
Hence, Option D is the correct answer.
It is best to label everything. I color coded it for you to see better and understand.
