To find the slope from a graph of data for which a linear relation is expected, you should
A) use two nearby data points.
B) use two data points as far away as possible from each other.
C) use two nearby points on the best-fit line, which are not actual data points.
D) use two distant points on the best-fit line, which are not actual data points.
E) calculate the slope for every possible pair of data points, and average the values.

Question

Using two distant points on the best-fit line, which are not actual data points, provides a more accurate representation of the overall trend of the data by minimizing the impact of any individual outlier or small-scale variation. This method ensures that the calculated slope reflects the general direction and rate of change of the entire dataset.
