Answer :
Final answer:
To calculate the slope for a line passing through (1, 0.1) and (7, 26.8), use the formula (y2 - y1) / (x2 - x1). The calculated slope is 4.5. Therefore, the correct option is B.
Explanation:
To find the slope of a line that passes through two points, Point 1: (1, 0.1) and Point 2: (7, 26.8), you must use the slope formula which is slope (m) = (y2 - y1) / (x2 - x1). Plugging in the given points: (26.8 - 0.1) / (7 - 1), you get 26.7 / 6 which simplifies to 4.45. Therefore, the correct slope would be 4.5, which corresponds to option b.
