The boundary point is the at the edge of a .
The boundary point for the inequality is
A boundary line
is a that defines the edge of an area. Usually, this refers to the line that splits a plane in half in the graph of a .
In the example above, the line
is the boundary line of the inequality
A boundary curve
is the same as a boundary line in every way except that the word
can be used to describe inequalities whose boundaries are not .
In this example, the curve
is the boundary curve of the inequality
