They are parallel lines
If they are not parallel and do not intersect then they would not be in the same plane (not possible), but they would be called skew lines.
They are called skew lines.
a Cartesian Coordinate plane
They are parallel lines
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
If the two lines lie in the same plane, and they do not intersect, then they are parallel. If they are not in the same plane, and do not intersect, then they are called skew lines.

They are parallel lines
Two lines that are in the same plane and never intersect are called "Parallel," meaning that they are lines with the same slope, but not y-intersect.
If they are not parallel and do not intersect then they would not be in the same plane (not possible), but they would be called skew lines.
