Answer
All the points are in the form of $(3,y,1)$, where $y$ is any real number.
Work Step by Step
Since $x$ is set to $3$ and $z$ is set to $1$, we have a line parallel to the y-axis that passes through the point $(3,0,1)$. Thus, all the points are in the form of $(3,y,1)$, where $y$ is any real number.
