If $\mathbf { b } = \langle 1,0,1 \rangle$ $\mathbf { c } = \langle 0 , - 1,1 \rangle$

Short Answer

If $\mathbf { b } = \langle 1,0,1 \rangle$ , $\mathbf { c } = \langle 0 , - 1,1 \rangle$ , and $\mathbf { a } = \langle 2 , - 3 , z \rangle$ , find a value for z which guarantees that a, b, and c are coplanar.
