Answer 1

[❤NgocAnh❤]

\(\left|Ya-Yb\right|\)

\(=\left|-\left(m-1\right)-\left(-4\right)\right|\)

\(=\left|-m+1+4\right|\)

\(=\left|-m+5\right|=\left|5-m\right|\)

Vậy \(\left|Ya-Yb\right|=\left|5-m\right|\)

Answer 2

[Trần Ái Linh]

`|Ya - Yb| `

`= |(-(m-1) - (-4) |`

`= | -m +1 + 4|`

`=|-m+5|`

`= |5-m|`
