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 y-intercept is the value of y where an equation crosses the y-axis and x = 0. In the equation y = mx + b, if one substitutes 0 for x, the equation becomes y = b.
