Answer: 0.5

Work Shown

slope = rise/run

slope = (change in y)/(change in x)

slope = (y2 - y1)/(x2 - x1)

slope = (4 - 9)/(-2 - 8)

slope = -5/(-10)

slope = 0.5

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
