What is a straight line that attempts to predict the relationship between two points, also known as a trend line or line of best fit?

If there is a very strong correlation between two variables then the correlation coefficient must be

Square of average error is directly proportional to the dispersion of the sign in the general aggregate and is inversely proportional to size of sampling
