Explanation:
To find the slope of the line, we need to select any two points on the line and then use the slope formula:
slope = (y2 - y1) / (x2 - x1)
Let's choose the points (-2, 6) and (2, -6) on the line. Then, we can calculate the slope as:
slope = (-6 - 6) / (2 - (-2))
slope = -12 / 4
slope = -3
Therefore, the slope of the line is -3.
