To find the slope of the line passing through the points \( A = (-2, 6) \) and \( B = (2, -2) \), we can use the formula for the slope \( m \), which is given by:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
In this case, we can label the coordinates as follows:
- \( (x_1, y_1) = (-2, 6) \)
- \( (x_2, y_2) = (2, -2) \)
Now, substituting these values into the slope formula:
\[ m = \frac{-2 - 6}{2 - (-2)} = \frac{-2 - 6}{2 + 2} = \frac{-8}{4} = -2 \]
Therefore, the slope of the line is \( \boxed{-2} \).
