To calculate the slope of the line defined by the given points, we can use the slope formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
We can take any two points from the list. Let's use the points (-3, 49) and (0, 43).
Here, \( (x_1, y_1) = (-3, 49) \) and \( (x_2, y_2) = (0, 43) \).
Now, substituting these values into the slope formula:
\[ m = \frac{43 - 49}{0 - (-3)} = \frac{-6}{3} = -2 \]
Thus, the slope of the line is \(-2\).
