When two values are directly proportional, what occurs?

When two values are directly proportional, it means that as one value increases, the other value also increases at a constant rate, or conversely, as one value decreases, the other value decreases as well. This consistent relationship maintains a fixed ratio between the two values.

For example, if you consider a simple scenario where the distance traveled is directly proportional to the time taken at a constant speed, doubling the time will result in doubling the distance. This relationship emphasizes that the two values work in conjunction with each other, enabling predictable outcomes.

The other options depict different relationships: one suggests an inverse relationship where one value’s increase leads to the other’s decrease, another implies a multiplicative relationship that does not characterize direct proportionality, and the last option indicates independence between the values, which contradicts the fundamental concept of direct proportionality where the values must influence each other.
