Explanation:
These are the 3 ways that two lines can relate to one another:
- The lines are parallel :

Parallel means they never intersect. They are at the same distance from one another so they never intercept each other.
- The lines are perpendicular :

The intersection of these two lines is at a right angle of 90°.
One line can be two lines. It's just that we can't see the second one since they combined to form one line. And they have an infinite number of common points and x- (or y-) intercepts.
Therefore, these are the ways.
