When given a set of data where the independent variable is time, it is possible to use statistical techniques to find a line (or curve) of best fit. One of the ways to do this is to minimise the square of the the differences between the actual values which are observed and the values that are predicted by such a curve (fitted values). The slope of this line or of the tangent to the curve at any point, is the least squares trend.
A statistical explanation of the theory or the calculations required are too much for the pathetic browser that we are required to use.

How do you find equation of trend line?
To find the equation of a trend line, you typically use a method called least squares regression. First, collect your data points and plot them on a scatter plot. Then, apply the least squares formula to calculate the slope and y-intercept of the line that best fits the data. The resulting equation is usually expressed in the form (y = mx + b), where (m) is the slope and (b) is the y-intercept.
How can you use a scatter plot to find an equation of a trend line?
By finding the line of best fit and using the straight line equation formula.

How can you find an equation for a trend line?
There are numerous ways to do this. I think the easiest is to put the data in excel and have excel show the trend line, equation, andcorrelation coefficient. Excel gives you several options to choose for the trend line analysis. The other way is if it is a linear relationship, you can do the linear regression analysis following the steps listed in the related link. If you are not familiar with regression analysis, it may not be easy for you to follow.
What is an equation that contains at least one variable?
An equation that contains at least one variable is (2x + 5 = 15). In this equation, (x) is the variable, and the equation states that when you multiply (x) by 2 and add 5, the result equals 15. Solving for (x) will allow you to find its value.
