How to interpret the slope of a trend line
WebThe slope of a line is the rise over the run. If the slope is given by an integer or decimal value we can always put it over the number 1. In this case, the line rises by the slope when it runs 1. “Runs 1” means that the x value increases by 1 unit. Therefore the slope represents how much the y value changes when the x value changes by 1 unit. Web11 apr. 2024 · Often you may want to find the slope of a trendline in Excel.
