Answer:
-1/3
Step-by-step explanation:
Use the formula, (y2 - y1)/(x2 - x1).  In this case, there is a negative slope.  
Start from point, (1, 9) and go to point (4, 8).  
Use the formula:
(y2 - y1)/(x2 - x1)
Y2 = 8
Y1 = 4
X2 = 9
X1 = 1
(8 - 9)/(4 - 1) = -1/3
Therefore, the slope is -1/3
  
        
                    
             
        
        
        
24 makes the equation true
        
             
        
        
        
The correct answer would be rectangle 'D'.
If we looked at rectangle 'E' and moved it to the left by 7 units (every unit = 1 square on the grid), we would arrive at a point. From then, we can move upwards 12 units and arrive at rectangle 'D'.
        
                    
             
        
        
        
Ok so logically it would be the blue which is consistently low and unlike the others doesn't get any spikes of interst so BLUE.
 
        
                    
             
        
        
        
Answer: The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept.
