To find the slope of the line that passes through the points (3, 2) and (5, 7), we can use the formula for the slope \( m \):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Here, \( (x_1, y_1) = (3, 2) \) and \( (x_2, y_2) = (5, 7) \).
Now, substituting in the values:
\[ m = \frac{7 - 2}{5 - 3} \]
This simplifies to:
\[ m = \frac{5}{2} \]
Therefore, the slope of the line that passes through the points (3, 2) and (5, 7) is \( \frac{5}{2} \).
