Answer:
"The length of the resulting line segment is 20 units because translations preserve length"
Step-by-step explanation:
A translation, in maths, is the movements of a geometric shape/line in certain direction. There is no rotation, re-sizing, or alteration. It simply "moves" the line/shape in a direction. The length is not altered in any way. Translation preserves length, every point just changes place.
When we translate a figure/line, we are simply moving it elsewhere, keeping all else constant.
In this problem, the line segment at hand is 20 units and it is translated 6 units up and 8 units left. So the location of the line changes, but the length is preserved. So, 2nd answer choice is right:
"The length of the resulting line segment is 20 units because translations preserve length"
