Note:
In language of mathematics, when we work with two (or more) lines at one time, we can use subscripts to name the lines. The prefix sub means below or beneath, as in submarine or subway. To name the first line in the figure above, we use l1, which is read as "l sub one." To name the second line, we use l2, which is read as "l sub two."
