Linear Regression 0 { (Intercept/Slope)-Enables you to display the y-intercept and slope of the representative line. To display the y-intercept (b), press 0 {; to display the slope (a), press w after you display the y-intercept. 0 d (Correlation)-Calculates the correlation between the x and y values in a set of data points. 0 T, 0 Q (Predicted Value)-After you enter an x value, you can press 0 Q to display the y value that corresponds with that x on the best straight line through the data points entered. Similarly, after you enter a y value, you can press 0 T to display the corresponding x value. 29
