The equation of the regression line is Y= a+bX. Match to following the description to the right.

	X	Denotes the variable plotted on the horizontal axis and called the explanatory or independent variable
	b	Denotes the variable plotted on the vertical axis and is called the response or dependent variable.
	a	The regression result = the change in Y for a change in X of +1, and called the slope
	R	The proportion of the variability of Y that is explained by or accountable to X.
	Y	The Strength and direction of the linear relation ship between X and Y
	R2	The regression result = elevation of the line at X=0, and called the intercept
