Answer:
Option D.
Step-by-step explanation:
Consider the below figure attached with this question.
If a line passes through two points and
, then the equation of line is
From the below figure it is clear that the a solid line passes through the points (-2,0) and (0,4). So, the equation of related line is
All area above the solid line is shaded. It means the sign of inequality is ≥.
From the below figure it is clear that the a dashed line passes through the points (2,0) and (0,2). So, the equation of related line is
All area below the dashed line is shaded. It means the sign of inequality is <.
System of inequality is
Therefore, the correct option is D.
