In the example above I have opted to select the entire column in both cases because that means that the formula does not need to be adjusted even if additional data is added. ![]() Slope Function: Provides the slope or gradient of the line of best fit and its structure is Slope(Y values, X Values). ![]() The equation required to do this is as follows The first methods listed in this article will provide an Excel equation that will automatically produce the equation of the line of best fit or trendline in excel provided that the X values are placed in column A of the sheet and the Y values are placed in column B. M = the gradient or slope of the line, andĬ = the y-intercept which is the value of why at the point at which the line crosses the y-axis Method 1 – Calculating The Equation In A Cell ![]() Calculating Values for X and Y by Graphing | TI-83 Plus and TI-84 Plus Graphing Calculators
