michele_laino · Answer

the value of $r=0.999$ tells us that we can fit such experimental data with a straight line, so, we can write the formula of such line, by means of this formula:
$$y - \bar y = m\left( {x - \bar x} \right)$$

howard-wolowitz · Answer

ok, I see; so now we have to figure out the values right?

michele_laino · Answer

yes!
I think that the slope $m$, is:
$$\huge m = \frac{{{s_y}}}{{{s_x}}}$$
even if I'm not sure.
Please what is the meaning of $s_x$ and $s_y$?

michele_laino · Answer

After a substitution, I get:
$$\Large  y - 5.64 = m\left( {x - 1979.5} \right)$$

michele_laino · Answer

I think that $m$ can be this:
$$\Large  m = \frac{{{s_y}}}{{{s_x}}} = \frac{{0.718}}{{1.29}}$$
nevertheless, I'm not sure
