Answer:
To find the slope of a line passing through two points you can use the formula:
m = (y2 - y1) / (x2 - x1)
The coordinates of the first point are (x1, y1) = (1, 2), and the coordinates of the second point are (x2, y2) = (4, 3).
Substituting these values into the formula,
m = (3 - 2) / (4 - 1)
= 1 / 3
So, the slope of the line passing through (1, 2) and (4, 3) is 1/3.
