Find the slope of the line that passes through (1, 5) and (3, 8).

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)

In this case, the two points are (1, 5) and (3, 8).
Plugging in the values into the formula, we get:
m = (8 - 5) / (3 - 1)
= 3 / 2

Therefore, the slope of the line is 3/2.
