Answer:
B
Step-by-step explanation:
they want us to find the equation in slope intercept form 
which is y= mx + b 
where m = slope and b = y intercept
the slope is change in y over change in x
as y goes up 1 x goes up 1 so the slope is 1 or m=1
the y intercept is at point (0,1)
so the y intercept is 1
now we add it all together and get that the equation Is
y=x+1
 
        
             
        
        
        
Answer: 34
Step-by-step explanation:
times it 
 
        
                    
             
        
        
        
The population standard deviation, σ = 1.68, the sample standard deviation, s = 1.95, the sample mean =7.23,  and the sample size, n = 39.The test statistics is given by
T=(n - 1) (s / σ)²
= (39 - 1) (1.95 / 1.68)²
= 38 (1.35)= 51.196
        
             
        
        
        
The slope is

So, the equation is

The y-intercept is when x=0, so
