Final answer:
The slope of a line represents the rate of change of the line. It can be found by calculating the ratio of the vertical change to the horizontal change. In this case, the slope is 250 m/s.
Step-by-step explanation:
The slope of a line represents the rate at which the line is increasing or decreasing as you move along it. It can be found by calculating the ratio of the vertical change (rise) to the horizontal change (run). In this case, since the slope is constant, you can choose any two points on the line to find the slope.
Let's take the points (6.4 s, 2000 m) and (0.50 s, 525 m) as our example. The rise is 2000 m - 525 m = 1475 m, and the run is 6.4 s - 0.50 s = 5.90 s. Therefore, the slope of the line is 1475 m / 5.90 s = 250 m/s.
