Answer:
y = -1/2x
Step-by-step explanation:
The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0
The slope is -1/2 because as it rises by -10, it runs by 20
Slope is rise/run which is -10/20 which simplifies to -1/2
y = mx + b
b = y - intercept
m = slope
y = -1/2x + 0 or y = -1/2x

Answer:
Hence the degrees of freedom are associated with the critical value is 25.
Step-by-step explanation:
Using two independent samples, two population means are  
compared to determine if a difference exists, the population standard deviation is equal.  
sample size 1 =  = 15 and sample size 2 =
= 15 and sample size 2 =  = 12
 = 12  
since, population standard deviations are equal, required degrees of freedom               
 
  
 
        
             
        
        
        
Answer:
y = - 5x + 8
Step-by-step explanation:
Given that :
Intercept = 8
Slope = - 5
Recall, the general. Slope - intercept equation :
y = bx + c
Where;
b = slope ; c = intercept 
Plugging the Given slope and intercept values, equation becomes ;
y = - 5x + 8
