What does the sign of the slope mean in this context?

The sign of the slope indicates the direction of the relationship between the two variables being analyzed. A positive slope suggests that as one variable increases, the other variable also increases, indicating a direct relationship. Conversely, a negative slope indicates that as one variable increases, the other decreases, demonstrating an inverse relationship. Understanding the slope's sign helps clarify how changes in one variable affect the other in the context being studied.
