hartnn (hartnn):
what did you try?
know how to get \(\bar{CD} \) ?
OpenStudy (buckybarnes):
I don't know where to start on this I'm completely stuck.
hartnn (hartnn):
where are points C and D located on the number line ?

C is -9 and D is 7
hartnn (hartnn):
good!
so,
CD = 7 - (-9) = ... ?
(finding distane here is just subtracting the co-ordinates)
OpenStudy (buckybarnes):
I got 16
hartnn (hartnn):
yes,
CD = 16,
and we are given, CE/CD = 1/8
so,
CE/16 = 1/8
can you get CE ?
OpenStudy (buckybarnes):
How would I do that?

hartnn (hartnn):
multiply 16 on both sides
hartnn (hartnn):
CE = 1/8 *16 = 16/8 = ...
OpenStudy (buckybarnes):
I got 2?
hartnn (hartnn):
yes,
so C and E are just 2 units away!
C is at -9,
so where can E be?
(so that it is 2 units away from -9)
OpenStudy (buckybarnes):
-7?
