It does. Because 6+(-1) equals 5 and so does 19-14
        
                    
             
        
        
        
Answer:
-3/2
Step-by-step explanation:
Using the slope formula, we can find the slope of the line shown
m = ( y2-y1)/(x2-x1)
     = ( -1-3)/(-3-3)
    = -4/-6
   = 2/3
A line that is perpendicular is the negative reciprocal
-1/ (2/3) = -3/2
 
        
                    
             
        
        
        
Answer:
6.5%
Step-by-step explanation:
Percentage error formula = 
|Estimated value - Real value|/Real value × 100
From the above question,
Estimated value = 17,466
Real value = 16,400
Percentage error = |17,466 - 16,400|/16,400 × 100
= 1066/16,400 × 100
= 0.065 × 100
= 6.5%
Therefore, the percent error = 6.5%
