This is used to describe the variations in the value Y from the given changes in the values of X. So our y-intercept is literally just 2 minus 1. The regression equation for the above example will be.
Hence the regression line Y 428 004 X.
B 6 15206 3775 2417 6 23769 3775 2. So our y-intercept is literally just 2 minus 1. That just becomes 1. It can be expressed as follows.
