Final answer:
The slope of the line passing through the points (1, 0.1) and (7, 26.8) is 4.5.
Step-by-step explanation:
The slope of a line passing through two points can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
For the given points (1, 0.1) and (7, 26.8), the slope is calculated as follows:
slope = (26.8 - 0.1) / (7 - 1) = 4.5
Therefore, the slope is 4.5.
