50/80 = 0.625
100 - 0.625 = 0.375
0.375 = 37.5% (move the decimal point to the right 2 spaces)
37.5% decrease is your answer
hope this helps

It says that's 4 units distant from the another vertex. So, if a square is formed by 4 equal sides and 4 right angles, then you just have to add 4 units on x or y.
-> (2, 1) -> + 4 units on X
-> = (6, 1)
or
-> (2, 1) -> +4 units on Y
-> = (2, 5)
(2, 5) isn't an answer so the unique possible answer is (6, 1)
Answer: (6, 1)
