Final answer:
The slope of a line passing through two points can be calculated using the formula m = (y2 - y1) / (x2 - x1).
Step-by-step explanation:
The slope of a line can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. For example, if we have the points (1, 0.1) and (7, 26.8), we can calculate the slope as follows:
m = (26.8 - 0.1) / (7 - 1) = 26.7 / 6 = 4.45
So the slope of the line passing through those two points is approximately 4.45.
