Answer:
slope = -250
Step-by-step explanation:
Use the two points with the blue and beige segments.
The point to the right has coordinates (8, 6000).
the point to the left has coordinates (4, 7000).
slope = rise/run = (difference in y)/(difference in x)
slope = (6000 - 7000)/(8 - 4)
slope = -1000/4
slope = -250
