    Hello, matthewspj!

    Write the vector and parametric equations of the line
    passing through A(3, -1, 2) and parallel to the x-axis.

    The x-axis has the direction vector: . \langle 1,0,0\rangle

    The vector is: . \vec{v} \;=\;\langle3+t,\:\text{-}1,\:2\rangle

    The parametric equations are: . \begin{Bmatrix}x &=& 3 + t \\ y &=& \text{-}1 \\ z &=& 2 \end{Bmatrix}
