Answer: Choice A) 8 units

---------------------------------------
---------------------------------------

Step-by-step explanation:

Use the intersecting chords theorem to get

y*6 = 4*12
6y = 48
6y/6 = 48/6
y = 8

Therefore y is 8 units long.

Check:
y*6 = 4*12
8*6 = 4*12
48 = 48
our answer checks out
