However, you know that the generic first order step response given by: or. The graph of a linear function is a line with a constant slope. To calculate the slope, we will consider an interval between and , compute the ratio of average rate of change of the exponential function over this interval and then see what happens as the interval becomes very small. Here, for instance, the slope of y = 1 is zero. The "rule of 70" tells us it will also take 5 time intervals to double, but in this case each time interval is 20 years. Hi all, I have a dataset which consists of 2 columns. This calculator uses the following formula to derive the equation for the line of best fit. Trendlines, or best fit lines, help reveal linear relationships between variables. If you have a time series with a clear pattern, you could use moving averages — but if you don’t have a clear pattern you can use exponential smoothing to forecast.
