it is simple, since, according to the formula of @xMissAlyCatx we can compute the slope \(b\), as below: \[\huge b = r\frac{{{s_y}}}{{{s_x}}} = 0.999 \cdot \frac{{0.718}}{{1.29}} = ...?\]
Michele_Laino
  • Michele_Laino
next, once you got the value of \(b\), we can write the equation of the line of best fit, using this formula: \[\huge \begin{gathered} y - \bar y = b\left( {x - \bar x} \right) \hfill \\ \hfill \\ y - 5.64 = b\left( {x - 1979.5} \right) \hfill \\ \end{gathered} \]
Michele_Laino
  • Michele_Laino
so, please what is the slope \(b\)?

one second please

=-1979.5x

  • Michele_Laino
I got this: \[\huge b = r\frac{{{s_y}}}{{{s_x}}} = 0.999 \cdot \frac{{0.718}}{{1.29}} = 0.556\] please check such value
Michele_Laino
  • Michele_Laino
so, after a substitution, we get: \[\huge y - 5.64 = 0.556 \cdot \left( {x - 1979.5} \right)\] please simplify such equation
Howard-Wolowitz
  • Howard-Wolowitz
ok so we have to do each equation?
Howard-Wolowitz
  • Howard-Wolowitz
I'm sorry I was confused at first I thought it was one equation. I understand now
Howard-Wolowitz
  • Howard-Wolowitz
ok i got 22.486
Michele_Laino
  • Michele_Laino
If I apply the distributive property of multiplication, over addition, at the right side, I write this: \[\huge y - 5.64 = 0.556x - 1100.6\] now, please add \(5.64\) to both sides, what do you get?

i got -1094.96
