find the parametric equations of the line that passes through the point p(2,3,4)& parallel to the xzplane

To be parallel to the xz plane, y must be constant. In this case, the constant is y = 3.
There is more than one line parallel to the xz plane that passes through that point. If the z vs x slopes of the various possible slopes in the y=3 plane are denoted by m,
z  4 = m (x  2)
