已知数轴上表示负有理数m的点是点M,那么在数轴上与M相聚/M/个单位的点中,与原点距离较远的点对应的数是
已知数轴上表示负有理数m的点是点M,那么在数轴上与M相距|m|个单位的点中,与原点距离较远的点对应的数是?
设点为x,则
|x-m|=|m|
x-m=m或x-m=-m
所以
与负有理数m相距|m|个单位的点是2m和0
所以
与原点距离较远的点对应的数是2m.
与原点距离较远的点所对应的点:2m

已知点M表示负数m,所以点M在原点左边,
所以与M相聚/M/个单位的点中,与原点距离较远的点应在点M得左边,也是负数
因为/M/=/m/,
所以那么在数轴上与M相聚/M/个单位的点中,与原点距离较远的点对应的数是2m
已知数轴上表示负有理数m的点是点M,那么在数轴上与M相聚/M/个单位的点中,与原点距离较远的点对应的数是2m .
