    Scalar parametric equations for lines

    Find a set of scalar parametric equations for the line that satisfies the given condition:

    Passes through P(2, -2, 3) and perpendicular to the xz-plane.

    I know that I need direction numbers, but not sure how to find them.

    I may be wrong here, but do I start with an equation passing through P and perpendicular to xz-plane => y = -2?

    If the line is perpendicular to the xz-plane the x & z values are constant.
    Thus (2,-2+t,3) is the line.
