Question

If a line segment with endpoints (6, 3) and (6, 7) is translated 3 units up and 4 units to the right, how long is the line segment after the translation?
A. 0 units
B. 10 units
C. 4 units
D. There is not enough information to measure the line segment.

Answer 1

Distance between (6,3) and (6,7) is sqrt((6-6)^2+(7-3)^2)=4. A translation doesn't change length, so the segment is still 4 units long. Answer: C.
