Final answer:
The slope of a zip line can be determined by calculating the rise over run between two points on the line. If Dummett used two points to determine the plans for the zip line for Sean, then the slope is consistent.
Step-by-step explanation:
The slope of a zip line can be determined by calculating the rise over run between two points on the line. Any two points on the line can be used to find the slope, as long as they are not the same point. In this case, if Dummett used two points to determine the plans for the zip line for Sean, then the slope is consistent.
For example, let's consider two points on the zip line: (6.4 s, 2000 m) and (0.50 s, 525 m). We can calculate the slope by finding the rise, which is the change in the vertical distance (525 m to 2000 m), and the run, which is the change in the horizontal distance (0.50 s to 6.4 s). The slope will be the ratio of the rise to the run.
Therefore, the correct answer is: a) Yes, the slope is consistent.
