The boundary point for the strict inequality $x\gt 4$ is $4.$

In the example above, the line $y=x$ is the boundary line of the non-strict inequality $y\leq x.$

curvecan be used to describe inequalities whose boundaries are not linear functions.

In this example, the curve $y=x^2$ is the boundary curve of the strict inequality $y\gt x^2$
