Equation of the line which passes through the point with position vector

(2, 1, 0)

and perpendicular to the plane containing the vectors

\mathbf{i} + \mathbf{j}

and

\mathbf{j} + \mathbf{k}

is Where,

t

is a parameter. a.

\mathbf{r} = (2, 1, 0) + t(1, -1, 1)

\mathbf{r} = (2, 1, 0) + t(-1, 1, 1)

\mathbf{r} = (2, 1, 0) + t(1, 1, -1)

\mathbf{r} = (2, 1, 0) + t(1, 1, 1)
