On a graph of position versus time, what physical quantity does the slope of the line represent?

1. A straight-line graph has the general form y = mx + b, where m is the slope (rise over run). 2. On a position-vs-time graph, the rise is the change in position (displacement) and the run is the change in time. 3. The text states this relationship directly: "the slope in a d versus t graph, is the average velocity." 4. So the slope of a position-time graph gives average velocity, not acceleration, distance, or time by itself. _Source: OpenStax Physics Ch 2 "Motion in One Dimension", p.72 §2.3 Position vs. Time Graphs_
