Answer:
16
Explanation:
The segments are parallel when their slopes are the same. The slope of each can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
You want ...
(14 -7)/(20 -15) = (y -2)/(33 -3)
7/5 = (y -2)/10 . . . simplify
14 = y -2 . . . . . . . . multiply by 10
16 = y . . . . . . . . . . add 2
y = 16 will make the segments parallel.
