An inventory manager is evaluating two proposed adjustments to stock levels, represented by the ordered pairs $({}-2, 1)$ and $({}4, -1)$. These adjustments must satisfy a system of storage constraints defined by:

${}y > 4x - 2$ ${}4x - y < 20$

Based on the mathematical verification of these points, which of the following conclusions is correct?

An operations manager is assessing a new production schedule where the planned adjustments to labor hours ($x$) and material costs ($y$) are bounded by a system of constraints: $y > 4x - 2$ and ${}4x - y < 20$.

True or False: The proposed adjustment $(4, -1)$ is a valid solution to this system because it successfully satisfies the second inequality (${}17 < 20$), even though it fails the first inequality ($-1 > 14$).

Verifying System Solutions via Substitution

A logistics coordinator is verifying if specific shipment coordinates (x, y) satisfy a system of safety constraints defined by: $y > 4x - 2$ and ${}4x - y < 20$. Arrange the procedural steps in the correct order to determine if a coordinate pair, such as $(-2, 1)$, is a valid solution to this system.

Verification of Operational Parameters

As an operations supervisor for a logistics firm, you need to verify if proposed fleet route adjustments—represented by the coordinate pairs $({}-2, 1)$ and $({}4, -1)$—satisfy the company's efficiency and safety constraints. The system of constraints is defined by:

1. $y > 4x - 2$
2. ${}4x - y < 20$

Match each route coordinate pair or substitution step with its correct operational validation result.
