Answer 9

The regression line is of the form y=ax+b, and the parameters a, b can be found using formulas given in step 2 of the following link:
http://www.statisticshowto.com/how-to-find-a-linear-regression-equation/
this assumes that you have the data of the whole population.
If your data represent a sample, the resulting regression line is just an approximate one.

Answer 14

The equation says:
Let the regression line be y=ax+b, and
n=number f data points
then
\(\Huge a=\frac{n\Sigma xy-\Sigma x \Sigma y}{n\Sigma x^2 - (\Sigma x)^2}\)
\(\huge b=\frac{\Sigma y}{n}-a\frac{\Sigma x}{n}\)

(note: I do not use the same notations as in the link.)

To calculate \(\Sigma x, \Sigma y, \Sigma x^2, \Sigma xy\) you would be well advised to create a table and add at the bottom of each column, or better still, use Excel.
