It is a mistake to belie1v 8nyjl ah,bsyn 2/a7ve that all graphs must go through the origin. In physics many 1,jalvn/7yya2n s8 h bdo not. But the scatter of the points suggests there are significant random errors. The fact that the line of best fit does not go through the origin can only be taken of evidence of a systematic error only if there is good theoretical reason to believe that the line must go through the origin.
