Final answer:
The slope of the line through points (8, 2) and (10, 2) is 0, indicating a horizontal line.
Step-by-step explanation:
The slope of a line can be found using the formula Δy/Δx, which is the change in y-values divided by the change in x-values. To find the slope of the line passing through the points (8, 2) and (10, 2), use the formula:
slope = (y2 - y1) / (x2 - x1) = (2 - 2) / (10 - 8) = 0 / 2 = 0.
Therefore, the slope of the line passing through these two points is 0, indicating that it is a horizontal line.
