Yes, in the context of graphing equations and coordinate systems, the x-axis represents the horizontal axis, and it is often referred to as the "run." The y-axis represents the vertical axis, and it is often referred to as the "rise."
When you move along the x-axis, you are changing the horizontal position, which can be thought of as the "run." When you move along the y-axis, you are changing the vertical position, which can be thought of as the "rise."
In slope-intercept form, where a linear equation is written as y = mx + b, with m representing the slope, the coefficient of x is often thought of as the "run" because it determines how much the line rises (or falls) for each unit of run.
The slope of a line is calculated as the rise (change in y) divided by the run (change in x). In the context of linear equations and graphs, x is typically associated with the run, while y is associated with the rise.
I hope this clarifies the relationship between x (run) and y (rise) in the context of linear equations and graphs. Let me know if you need further clarification.
