Final answer:
In a scatterplot, the horizontal axis represents the independent variable, while the vertical axis depicts the dependent variable. These graphs are used to visualize relationships and trends between two variables.
Step-by-step explanation:
In a scatterplot produced by a Variable Coordinate System (VCS), the horizontal axis typically represents the independent variable, which is the factor that is intentionally varied or controlled during an experiment or observation. On the other hand, the vertical axis represents the dependent variable, which is the outcome or response that is measured and is thought to be influenced by the independent variable. For instance, if the relationship between time and distance is being analyzed, time would be plotted on the x-axis as the independent variable, while the distance from the station would be plotted on the y-axis as the dependent variable.
This description of axes is consistent across various types of scatterplots whether evaluating velocity directions (vx and vy), demonstrating constant acceleration on a v vs. t plot, or constructing a Time Series Graph. Scatterplots provide a visual representation of the relationship between two variables and are crucial for analyzing trends, patterns, and potential correlations between them.
