The formula for the slope of a line is accurately represented by the expression that calculates the change in the vertical direction (rise) over the change in the horizontal direction (run). Specifically, the slope, often denoted as "m," is calculated by taking the difference in the y-values (y2 - y1), which represents the rise, and dividing it by the difference in the x-values (x2 - x1), which represents the run.

This formula conveys how steep the line is or the rate of change between two points on that line. The rise indicates how much the line goes up or down, and the run tells how far horizontally the line travels. Thus, using this correct formulation allows for a precise understanding of the line's steepness and direction in a coordinate system.

This conceptual understanding of slope is essential in various applications within aviation and engineering, such as analyzing trends in data, assessing performance metrics, and determining required adjustments in flight paths or maintenance procedures.
