##### 2 Answers

#### Explanation:

Suppose that the

As we are given a set of data points, we only need the slope *point-slope form* :

where

The slope of a linear equation is given by

Taking the first two points on the table, we get:

Thus, together with the point

We can also solve for *slope-intercept form* :

#### Explanation:

Given a list of values

a line can be adjusted such that the accumulated deviation error is minimum.

Let the line be given by

then the error at point

The accumulated quadratic error will be given by

solving for

appliying it to the table

we obtain:

so the adjusting line is
