The false statement about proportional relationships is:
**"Each point (or pair) in a proportional relationship must share the same difference."**
In a proportional relationship, the points share a constant ratio, not a constant difference. For example, in a proportional relationship defined by the equation \(y = kx\) (where \(k\) is a constant), the ratio \(\frac{y}{x}\) remains constant, but the difference \(y - x\) varies.
