Which term is used to describe the vertical axis on a graph?

The term that describes the vertical axis on a graph is the y-axis. In a typical Cartesian coordinate system, the y-axis runs vertically and is used to represent the dependent variable, while the x-axis, which is horizontal, usually represents the independent variable. This design is foundational in visual data representation, where the relationship between two variables can be analyzed.

Understanding the distinction between the axes is crucial in data-driven decision-making, as it helps in accurately interpreting graph plots and trends. The y-axis is essential for showcasing outcomes or results that change in response to variations along the x-axis, thus allowing for meaningful comparisons and interpretations in data analysis.
