## Proportionality Vs. Direct Variation

When distinguishing between proportionality and direct variation, it’s important to understand the fundamental differences in how they represent relationships between varying quantities. In proportionality, the relationship between two quantities is such that as one quantity changes, the other also changes, but their ratio remains constant. This means that if you were to graph the relationship between the two quantities, you’d see a straight line passing through the origin.

On the other hand, direct variation is a specific type of proportionality where the two quantities have a constant ratio and pass through the origin, but in this case, that constant ratio is equal to one. This implies that the two quantities increase or decrease together in a linear fashion. In essence, direct variation is a subset of proportionality, where the constant of proportionality is equal to one.

Understanding these distinctions can be crucial when working with mathematical models and real-world applications that involve varying quantities.
