For this case, the first thing we must do is take into account the definition of the axes: the x axis is time in seconds the y axis is velocity in meters per secon
Then, we look for the cut point with the y axis, which is given by: (0, 2) This means that the initial speed is 2 m / s.
We now look for the cut point with the x axis, which is given by: (8, 0) This means that the speed is 0 m / s, so the runner stopped when the time is 8 seconds.
Answer: The initial velocity of the runner was 2 m / s, and the runner stopped after 8 seconds.
