Find the value of a parameter \( a\in\mathbb{R} \) so that the point \( D=[-2;1;1] \) lies on the straight line \( p \) defined by the parametric equations \[\begin{aligned}p\colon x&=1+m,\\ y&=-2+m,\\ z&=a+m;\ m\in\mathbb{R}. \end{aligned}\]
no such values of \(a \) exists
\( a=-1 \)
\( a=0 \)
\( a = 1\)
