Locate one other point on the trend line. Then find the slope of the trend line.
...How do I do that?

Divide the change in y (the vertical axis value) by the change in the x-axis value (which may represent time).

3b. Pick any two points on the line and find the slope of the line.
The slope is a numerical value that describes just how slanted a given line is.
Here is is an example of finding the slope of a line.
Given the points (3, 4) and (8, 9), find the slope.
The symbol for slope is the letter m.
Let m = slope.
We now subtract b from d and a from c.
(a,b) = (3,4)
(c,d) = (8,9)
m = (9 - 4)/(8 - 3)
m = 5/5
m = 1
The slope is 1.
