Final answer:
The slope of a line passing through the points (2,8) and (4,6) is calculated using the formula for slope and equals -1, which corresponds to Option 2.
Step-by-step explanation:
The slope of a line passing through two points (2,8) and (4,6) can be found using the slope formula:
Slope (m) = (y2 - y1) / (x2 - x1)
Using the given points:
Slope (m) = (6 - 8) / (4 - 2) = (-2) / (2) = -1
Therefore, the correct answer is Option 2: Slope = -1.
