Answer:

Explanation:

1.Check their slopes and y-intercepts: if the two lines have the same slope, but different y-intercepts, then they are parallel.

2.Check the distance between them: if two lines always have the same distance between them, then they are parallel.

3.Check the angles from a transversal: if a transversal intersecting the two lines forms congruent corresponding angles, then the lines are parallel
