Final answer:
The slope of the line passing through the given points (1, 0.1) and (7, 26.8) is calculated as 4.45, which approximates to 4.5.
Step-by-step explanation:
The slope of a line passing through two points can be found using the formula m = (y2 - y1) / (x2 - x1), where m represents the slope, (x1, y1) and (x2, y2) are the coordinates of the two points. In this case, we have Point 1: (1, 0.1) and Point 2: (7, 26.8).
Using the slope formula, we have:
m = (26.8 - 0.1) / (7 - 1) = 26.7 / 6 = 4.45, which rounds to 4.5.
So, the slope of the line passing through the given points is approximately 4.5.
