Answer :
Answer: 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.
Final answer:
The line can be named in 3 different ways: k, DE, and ED. These names allow us to refer to the same line using different representations. option A is the correct answer.
Explanation:
The line can be named in 3 different ways: k, DE, and ED. So, option D is the correct choice. The names k, DE, and ED represent the line using different notations. For example, if you name the line as k, you are using a single lowercase letter to represent it. If you name it as DE or ED, you are using two uppercase letters. These different names allow us to refer to the same line using different representations.
