Two lines are coplanar if they both have 2 points in the same plane. So in an X,Y,Z
grid, one slope, be it X Y or Z, must be the same for both lines. To find the slope,
use Y1-Y2/X1-X2 or replace one of those values with Z. For this particular example,
it doesn't matter which is on the numerator, because it is a comparison.
================================
Short-cut:
Two lines that intersect are always coplanar.
yes, two lines can be coplanar.
No. If two lines intersect, then they're definitely coplanar.
No, not always. Skew lines are never coplanar, but parallel lines are.
Parallel lines.

yes, two lines can be coplanar.
are two lines that are not parallel, coplanar, and do not intersect
No. If two lines intersect, then they're definitely coplanar.
No, not always. Skew lines are never coplanar, but parallel lines are.
Two coplanar lines that never intersect are called called parallel lines.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.

Parallel lines.
Parallel Lines or Skew Lines.
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
