Find the slope of the line that passes through (5, 2) and (10, 4).

Simplify your answer and write it as a proper fraction, improper fraction, or integer.

The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula:

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

Substituting the given points (5, 2) and (10, 4) into the formula, we have:

m = (4 - 2) / (10 - 5)

Simplifying this expression yields:

m = 2 / 5

Therefore, the slope of the line is 2/5.
