Final answer:
To calculate the slope of the line between 6.0 seconds and 8.0 seconds, we choose two points on the line and apply the formula slope = (change in y) / (change in x). In this case, the slope is 250 m/s.
Step-by-step explanation:
To calculate the slope of the line between 6.0 seconds and 8.0 seconds, we need to choose two points on the line. Let's use the points labeled on the graph: (6.4 s, 2000 m) and (0.50 s, 525 m).
To find the slope, we use the formula: slope = (change in y) / (change in x). In this case, the change in y is 2000 m - 525 m = 1475 m, and the change in x is 6.4 s - 0.50 s = 5.90 s. So, the slope is 1475 m / 5.90 s = 250 m/s.
