An illustration shows a coordinate plane with the x-axis ranging from negative 9 to 9 in one unit increments, and the y-axis ranging from negative 11 to 11 in one unit increments. A solid line passes through four plotted points and extends beyond. A solid line with arrows at both ends passes through points with coordinates left parenthesis 0 comma 0 right parenthesis, left parenthesis 2 comma negative 2 right parenthesis, left parenthesis 4 comma negative 4 right parenthesis, and left parenthesis 6 comma negative 6 right parenthesis. The solid line forms the hypotenuse for two triangles. The first triangle is marked with a dotted line and has vertices with coordinates left parenthesis 0 comma 0 right parenthesis, left parenthesis 0 comma negative 2 right parenthesis, and left parenthesis 2 comma negative 2 right parenthesis. The base is labeled as 2, and the perpendicular height on the left is labeled as 2. The second triangle is marked with a dashed line and has vertices with coordinates left parenthesis 2 comma negative 2 right parenthesis, left parenthesis 2 comma negative 6 right parenthesis, and left parenthesis 6 comma negative 6 right parenthesis. The base is labeled as 4, and the perpendicular height on the left is labeled as 4.

To find the slope of the line that passes through the points \((0, 0)\) and \((2, -2)\), you can use the formula for slope, which is given by:
\[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} \]
Substituting the points \((0, 0)\) as \((x_1, y_1)\) and \((2, -2)\) as \((x_2, y_2)\):
\[ \text{slope} = \frac{-2 - 0}{2 - 0} = \frac{-2}{2} = -1 \]
Thus, the slope of the line is \(-1\).
The correct response is:
