As a mathematical concept, the term "run" is often used in the context of linear equations and the study of lines, particularly when discussing the slope of a line. The slope is a measure of the steepness of a line and is determined by how much the line rises vertically (the rise) for a given horizontal distance (the run). Understanding the concept of "run" is fundamental to grasping the relationship between the slope and the equation of a straight line.
In a linear equation, the "run" refers to the horizontal change, or the distance that a line travels along the x-axis for each unit of vertical change, which is the rise. It is one part of the slope's ratio, where the slope is the rise divided by the run. The slope is a key concept in the field of geometry and is used to describe the angle at which a line inclines relative to the horizontal axis.
The slope of a line is a mathematical representation of the line's steepness. It is calculated as the change in y (the rise) divided by the change in x (the run). This is often represented algebraically as:
\[ \text{Slope} = \frac{\text{Rise}}{\text{Run}} \]
For instance, if a line rises 3 units for every 4 units it runs (or moves horizontally), the slope of the line would be:
\[ \text{Slope} = \frac{3}{4} \]
This means that for every 4 units the line moves to the right, it also moves up by 3 units.
The concept of "run" is also integral when discussing the equation of a straight line. The general form of a linear equation is:
\[ y = mx + b \]
Here, \( m \) represents the slope of the line, which is the ratio of the rise to the run, and \( b \) is the y-intercept, which is the point where the line crosses the y-axis.
Understanding the "run" is not just about calculating the slope; it also helps in visualizing the line's path. For example, a line with a greater run relative to the rise would be a flatter line, indicating a smaller angle of inclination with the x-axis. Conversely, a line with a smaller run relative to the rise would be steeper.
In summary, the "run" in mathematics is the horizontal distance a line covers for each unit of vertical rise. It is a fundamental part of the slope calculation and is essential for understanding the properties and behavior of lines in geometry.

more ... How far a line goes along (for a given distance going up). Rise/Run (Rise divided by Run) gives us the slope of the line. See: Slope. Equation of a Straight Line.
