Step $1$: Compute the Components of the Linear Regression Equation

$\stackrel{}{x}=\frac{92}{10}=9\mathrm{.}2\frac{?}{b}$

$ar(y)=\frac{128\mathrm{.}6}{10}=12\mathrm{.}86$

$b=\frac{\frac{{\displaystyle \underset{?}{\overset{?}{}}}}{b}ar(xy)-n(\stackrel{}{x})(\frac{?}{\text{b}\text{a}\text{r}}(y))}{{\displaystyle \underset{?}{\overset{?}{}}}{x}^2-n{\stackrel{}{x}}^2}=\frac{(1\mathrm{.}290\mathrm{.}3)-(10)(9\mathrm{.}2)(12\mathrm{.}86)}{(932)-(10)(9\mathrm{.}2{)}^2}$

$b=1\mathrm{.}25$

$a\frac{?}{b}=ar(y)-b\stackrel{}{x}=12\mathrm{.}86-(1\mathrm{.}25)(9\mathrm{.}2)$

$a=1\mathrm{.}36$
