Cho \(M \left( {1;2; - 1} \right), \, \,N \left( {0;3;4} \right). \) Phương trình \(MN \) là:
A.\(\dfrac{{x - 1}}{{ - 1}} = \dfrac{{y - 2}}{1} = \dfrac{{z - 1}}{5}\)
B.\(\dfrac{{x - 1}}{1} = \dfrac{{y - 2}}{1} = \dfrac{{z + 1}}{5}\)
C.\(\dfrac{{x - 1}}{{ - 1}} = \dfrac{{y - 2}}{1} = \dfrac{{z + 1}}{{ - 5}}\)
D.\(\dfrac{{x - 1}}{{ - 1}} = \dfrac{{y - 2}}{1} = \dfrac{{z + 1}}{5}\)
