Question: A linear regression line may be written with different symbols ( Y =; a + bX or sometimes written as Y = mX + b

A linear regression line may be written with different symbols ( Y =; a + bX or sometimes written as Y = mX + b ) If the linear equation takes the form Y = a + bX where X is the explanatory variable and Y is the dependent variable. Then, the slope of the line is b, and a is the intercept (the value of y when x = 0 . What element of the regression equation would provide information about the direction of the relationship
