本题详细解析:
It is a mistake to believe that all graphs must yqd 3apggkw 05bc2e:1 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 theoretical pwkagb ge3 5ycd1:20q reason to believe that the line must go through the origin.
