The value of the intercept, a, anchors the scatterplotâs regression line relative to the values of X and Y (and their coordinates) for the problem at hand. Oftentimes the intercept is a mathematical abstraction but it serves a function of adjusting predicted values of Y relative to the plot.
The intercept is theyvalue when xequals zero, which is 1.0 in the example. Be sure to look carefullyat the x-axis scale; if it does not start at zero, you might read o the interceptincorrectly. The slope is the change in yfor a one-unit change in x. Because theline is straight, you can read this o anywhere.
