![]() ![]() Slope and Intercept return a #DIV/0! error. For example, if the data points of the known_y's argument are 0 and the data points of the known_x's argument are 1: The difference between these algorithms can lead to different results when data is undetermined and collinear. The underlying algorithm used in the Slope and Intercept functions is different than the underlying algorithm used in the LinEst function. The equation for the slope of the regression line is as follows, where x and y are the sample means AVERAGE(known_x's) and AVERAGE(known_y's): If known_y's and known_x's are empty or have a different number of data points, Slope returns the #N/A error value. ![]() If an array or reference argument contains text, logical values, or empty cells, those values are ignored however, cells with the value zero are included. The arguments must be either numbers or names, arrays, or references that contain numbers. Known_x's - the set of independent data points. Known_y's - an array or cell range of numeric dependent data points. SyntaxĮxpression A variable that represents a WorksheetFunction object. The slope is the vertical distance divided by the horizontal distance between any two points on the line, which is the rate of change along the regression line. Returns the slope of the linear regression line through data points in known_y's and known_x's. ![]()
