Please help,

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.

SAMPLE:

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.
