To find the run of the slope between two points, you need to calculate the difference in the x-coordinates (the horizontal change) of the two points.
Given:
- Point A (3, 3)
- Point B (1, -1)
The run is calculated as follows:
\[ \text{Run} = x_2 - x_1 \]
Where \( (x_1, y_1) \) are the coordinates of point A, and \( (x_2, y_2) \) are the coordinates of point B.
Substituting the coordinates:
\[ \text{Run} = 1 - 3 = -2 \]
So, the run is \(-2\).
