Compute the least$-$squares regression line for the given data set.

x $345678$ y $8\mathrm{.}58\mathrm{.}41011\mathrm{.}311\mathrm{.}913\mathrm{.}1$ sigma x $=33,$ sigmay $=63\mathrm{.}2$

Based on the data, the following are computed: sigmax $=33,$ sigmay $=63\mathrm{.}2,$ sigmay$^2=199,$ sigmay$^2=683\mathrm{.}72,$ and sigmaxy $=365$ choose the following answer y $=5\mathrm{.}0648+\mathrm{.}9400$x y $=8\mathrm{.}5+\mathrm{.}9500$x y$=\mathrm{.}9943+5\mathrm{.}0648$x y$=5\mathrm{.}0648+\mathrm{.}9943$x
