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
