It is a mistake to believe that all graphs mb7 -x-h1s.o t,yjd/el ridpux*8g e1l ust go through the origin. In physics many do 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 theoreticah*/egl t,1rolx. d8uij-1ex pb yd7 s-l reason to believe that the line must go through the origin.
