Hi.

Should the line of best fit extend across the whole graph paper, or should it stop at the x coordinates of the endpoints?

Thanks

To be honest, I have seen both. I usually stop at x-coordinates though to be on the safe side but I have only seen in one instance in a trial paper it had the marking guidlines as would loose a mark for not extrapolating line of best fit. I'm sure the question had mentioned it though or something along those lines so +1 pikachu just stop at x-coordinates and only extrapolate if necessary
