Answer:
-6
Step-by-step explanation:
You need to get it in Point-Slope form, or
y = mx + b
Isolate y by subtracting 6x
You are left with:
y = -6x + 24
M is the slope, so in this case, it is -6
 
        
                    
             
        
        
        
One inch of board is left
if you subtract the two 3 inches pieces from the board 
the further subtract the 24 inches from the three 8 inches pieces you get 31-30
