Answer: The objects instantaneous velocity at that point
Step-by-step explanation:
On a position versus time graph, the displacement is the vertical difference between two points and the time interval is the horizontal difference.
The ratio of displacement to time interval is the the objects instantaneous velocity at that point. This ratio is also the slope of the line.
Hence, The slope at a point on a position versus time graph of an object is the objects instantaneous velocity at that point.
