Well, since the line's two end points are W and L, I would say A is correct. Given the fact that the vertex is R, you could simply call the line Line R, which is C. If you were saying the line was WR, that would make it so you were talking about that half of the line, and not the part that hits the point L. I hope this helps. :)

thanks!

wait so A and C?

OpenStudy (e.mccormick):

Mava, in math, lines do not have end points. Only segments do. There is the simple definition that any two points define a line. Therefore, as long as proper notation is used and two points are involved, it describes the line. The infinite other points, defined or not, are inconsequential to this. So you have done things correctly as long as you use proper notation and any two of W, R, and L.

Yes, and no problem! :)
