In a simple regression analysis (where y is a dependent and x an independent variable), if the y-intercept is positive, then it must be true that .

Where:  

And we can find the intercept using this:  

On this case the correct answer would be:

E.  none of the above

Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable

Step-by-step explanation:

Assuming the following options:

A.  there is a positive correlation between X and Y

B.  there is a negative correlation between X and Y

C.  if X is increased, Y must also increase

D.  if Y is increased, X must also increase

E.  none of the above

If we want a model where m represent the lope and b the intercept

Where:  

And we can find the intercept using this:  

On this case the correct answer would be:

E.  none of the above

Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
