Find a solution to the following 5 points for the best fitting
linear equation (equation for a straight line) that "fits" the
points and gives a Sum of Squares of Deviations that is less than 6.

(2, 10)       a
(3.5, 6)      b
(5, 4)        c
(6, 2)        d
(8.6, 1)      e

The following list of the 5 points is convenient so you can COPY and PASTE
them into the Data Flyer tool, instead of having to type them.

2  10
3.5   6
5    4
6   2
8.6  1

What is the equation for the line?   y = mx + b  or  f(x) = mx + b

What is the SLOPE m that you got?

What is the INTERCEPT b that you got?

What is the exact Sum of squares of deviation you got with
                                 your equation y = mx + b?

Suppose you wanted to get a good estimate for the slope to try
first in the function.

Which two points would be best to choose?

a   and   b
c   and   e
d   and   e
a   and   e

What is the slope that the BEST choice gives you?   SHOW YOUR WORK!


Which two points would be the WORST to choose to get an estimate
of the slope for the best fitting line for the 5 points?

a   and   b
c   and   e
d   and   e
a   and   e

What is the slope that the WORST choice gives you?   SHOW YOUR WORK!
