WebIn simple linear regression, the predictions of Y when plotted as a function of X form a straight line. If the data is not linear, the line will be curvy through the plotted points. The basic formula for a regression line is Y’ = bX + A, where Y’ is the predicted score, b is the slope of the line, and A is the Y-intercept.
