Given:
The boundary line of an inequality is:
The solution set contains (0,0).
To find:
The inequality.
Solution:
The boundary line of an inequality is
Since (0,0) is in the solution set, therefore (0,0) satisfies the required inequality.
Taking LHS, we get
Substitute x=0 and y=0.
The right hand side of the given equation is 6.
We know that,
The boundary line is not a dotted line, it means the points on the boundary line are also included in the solution set. So, the inequality sign must be .
Therefore, the required inequality is .
