A Trend Line is defined as a "Straight or curved line in a trend chart that indicates the general pattern or direction of a time series data (information in sequence over time)."
It may be drawn visually by connecting the actual data points or (more frequently) by using statistical techniques such as 'exponential smoothing' or 'moving averages.'
Trend Lines are extremely helpful because they allow you to review historical data and generate forecasts.
