The equation provided is in point-slope form, which is given by:
\[ y - y_1 = m(x - x_1) \]
where \( m \) is the slope and \( (x_1, y_1) \) is a point on the line.
In the equation \( y - 1 = \frac{2}{3}(x - 6.5) \), we can identify the slope \( m \):
\[ m = \frac{2}{3} \]
Therefore, the slope of the line is \( \frac{2}{3} \).
