Mean of `x = barx = square`
Mean `y = bary = square`
`b_(xy)=(square)/(square)`
`b_(yx)=(square)/(square)`
Regression equation of `x` on `y` is `x-barx = b_(xy )(y-bary)`
`:.` Regression equation of `x` on `y` is `square`
Regression equation of `y` on `x` is `y - bary = b_(yx) (x - barx)`
`:.` Regression equation of `y` on `x` is `square`
