Hi there. Yep, if it doesn't specify a number of decimals places, you can leave it in fraction form if you prefer that. Cheers :)

Hiya. Yep, if the question doesn't specify they want the answer in decimals, you can leave it in fraction form :)

@palepumpkin They have to all fall exactly, perfectly on the line for that to work. If they're really close to being on the same line but they're not quite, then you'd need to slide 1/3 way towards that middle median, even if its not very far away at all. On an exam I expect they'll either give you something that's obviously all on the same line, or something that's obviously not and you have to slide your ruler over towards that middle median. It should be pretty clear from the Q. Cheers! :)

why are three median regression lines and least square regression different?
