Final answer:
The slope of the distance versus time graph, which represents the velocity, is 7 meters per second, calculated by dividing 14 meters by 2 seconds.
Step-by-step explanation:
The slope of the distance versus time graph represents the object's velocity. Since the student's example has an object that moves 14 meters every 2 seconds, we can calculate the slope by dividing the change in distance (14 meters) by the change in time (2 seconds). The slope of the line, which is the velocity, would therefore be 7 meters per second (14 m / 2 s = 7 m/s).
