The second issue is that sometimes the number of significant digits displayed in the formula on the chart is very limited. However, if you change the data set used to obtain the equation, that equation you manually entered will not update, leaving your spreadsheet with an erroneous equation. If you want to use that equation anywhere in your spreadsheet, you have to manually enter it. The first is that the equation displayed on the chart cannot be used anywhere else. The chart trendline method is a quick way to perform a very simple linear regression and fit a curve to a series of data, but it has two significant downfalls. Linear Regression with the LINEST function Now we know that the data set shown above has a slope of 165.4 and a y-intercept of -79.85. We’d follow these 6 steps (in Excel 2016): Let’s say we have the data set below, and we want to quickly determine the slope and y-intercept of a best-fit line through it. You can go from raw data to having the slope and intercept of a best-fit line in 6 clicks (in Excel 2016). Add the equation to the trendline and you have everything you need. When you need to get a quick and dirty linear equation fit to a set of data, the best way is to simply create an XY-chart (or “Scatter Chart”) and throw in a quick trendline.
