How many different ways can the line be named? What are those names? A. 3 ways;k, DE ED
B. 3 ways;k, DE ED
C. 2 ways;k, DE
D. 2 ways;k, DE, ED

A. 3 ways: k, DE, ED (both DE and ED have line markers over top)

To name a line, we just need two points on the line. We list them in any order because the line extends forever in both directions. Contrast this with a ray where order does matter. The little k is another way to name a line, potentially simplifying things.

Choice B is close, but it mentions ray DE instead of line DE. Choice C is missing line ED. Choice D is a similar story as choice B. These facts allow us to rule out B through D.
