Solution
Find Regression line xbar=39.5,ybar=47.5,SDx=10.8,SDy=15,r=0.42

Solution:
Your problem `->` Regression line xbar=39.5,ybar=47.5,SDx=10.8,SDy=15,r=0.42


`byx = r * (sigma y)/(sigma x)`

`byx = 0.42 * 15/10.8`

`byx = 0.5833`


Regression Line y on x
`y - bar y = byx (x - bar x)`

`y - 47.5 = 0.5833 (x - 39.5)`

`y - 47.5 = 0.5833 x - 23.0417`

`y = 0.5833 x - 23.0417 + 47.5`

`y = 0.5833 x + 24.4583`
