Consider the data set of decimal numbers:

2.20, 2.30, 2.30, 1.70, 2.00, 1.50, 2.40, 2.40, 2.00, 2.00, 2.00

Create a line plot to show the data. How many marks would be above 1.50?

A. 0
B. 1
C. 2
D. 4

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.
