     A negative relationship between two variables means that for the most part, as the x variable increases, the y variable increases.  A correlation coefficient of -1 implies a perfect linear relationship between the variables.  The strength of the linear relationship between two quantitative variables is determine by the value of  The equation of the regression line used in statistics is  A statistical graph of two quantitative variables is called a(n)  The x variable is called the  variable.  The range of r is from  to The sign of r and  will always be the same.  The regression line is called the  if all the points fall on a straight line, the value of r will be  Determine what the following r values mean. Calculate and interpret r^2.
