Medal for best explaination.
Which of the following equations could be the trend line of variables that have a negative correlation?
y = 2x + 1
y = x + 1
y = 2x  1
i know that its the first one & that m is the slope what is c? And how do i make this equation if im looking at a scatter plot. (posting one for an example)
