Final answer:
The slope of the line passing through the points (1, 2) and (5, 2) is 0.
Step-by-step explanation:
To find the slope of a line given two points, you can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, the two points are (1, 2) and (5, 2). Plugging the values into the formula, we get:
m = (2 - 2) / (5 - 1) = 0 / 4 = 0
Therefore, the slope of the line passing through the given points is 0.
