In a direct relationship, what happens to one quantity as the other quantity increases?

In a direct relationship, as one quantity increases, the other quantity increases as well. This means that both quantities move in the same direction. If you were to graph a direct relationship, you would see a straight line that slopes upward, indicating that an increase in one variable corresponds to a proportional increase in the other variable.

This concept is foundational in algebra and helps in understanding how variables interact with one another. For instance, if you consider a simple example of distance and time at a constant speed, as time goes up, the distance covered also goes up. This relationship holds true across various scenarios where two quantities are directly related, illustrating that the increase in one leads to a consistent increase in the other.
