Final answer:
The slope of the line passing through the points (8,9) and (-2,4) is 0.5.
Step-by-step explanation:
To find the slope of a line passing through two points, we use the formula:
slope = (y2 - y1) / (x2 - x1).
Given the points (8,9) and (-2,4), we can plug in the values into the formula to find the slope.
Slope = (4 - 9) / (-2 - 8) = -5 / -10 = 0.5.
Therefore, the slope of the line is 0.5.
The correct answer is A) 0.5
