It is a mistake to bj n n.f( +1 xzf)p63boqzfcazm(5il8believe that all graphs must go through the origin. In physics many do not. But the scatter 3nq+bn8z ioml )xfz5 ( z1cjb.f(p af6of 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.
