Final answer:
The slope of the line passing through the two given points is 4.45.
Step-by-step explanation:
To find the slope of the line passing through the two points, we can use the formula:
Slope = (y2 - y1) / (x2 - x1)
Given the points:
Point 1: (1, 0.1)
Point 2: (7, 26.8)
Plugging in the values, we get:
Slope = (26.8 - 0.1) / (7 - 1) = 26.7 / 6 = 4.45
Therefore, the slope of the line passing through the two points is 4.45. So the correct answer is b. 4.45.
