Give all possible names for the line shown. calculation tip: lines can be written with either point first.

Step-by-step explanation:

There are two possible names for the line

CD with the line bar over it ↔

DC with the line bar over it ↔

We need the line bar over it to indicate it is a line and not a line segment.  A line goes on infinitely in both directions while a line segment stops

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

answer: the answer is d
