A trend line is a mathematical equation that describes the relationship between two variables. It is produced from raw data obtained by measurement or testing. The simplest and most common trend line equations are linear, or straight, lines. Once you know the trend line equation for the relationship between two variables, you can easily predict what the value of one variable will be for any.

Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept. We've got a value for m and a value for b. This gives us the linear function. In many cases the value of b is not as easily read. In those cases, or if you're uncertain whether the line actually.
