The graph displays a straight line with two points clearly marked: (0, 2) and (2, 0).
The formula for the slope (m) of a line passing through two points (x1, y1) and (x2, y2) is:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Substituting the coordinates of the given points:
\[ m = \frac{0 - 2}{2 - 0} = \frac{-2}{2} = -1 \]
Answer: The slope of the line is -1.
