Answer:
-25
Step-by-step explanation:
You must first pick two points.  I picked the points of (4, 400) and (8, 300).  You can pick different points and still get the right answer.
Subtract the y's and the x's.  Divide the difference of y by the difference of x.
400 - 300 = 100
4 - 8 = -4
100/-4 = -25
The slope, or rate of change, is -25.
 
        
             
        
        
        
I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape. 
Then add all the areas together.
