Answer:
No.
Step-by-step explanation:
No, as long as you use the correct formula which is
√[(y2 - y1)^2 + (x2 - x1)^2].
If for example the 2 points are (1,6) and (-2,-5) and
we let (x1, y1) be (1, 6) and (x2,y2) be (-2,-5) the length is
√(-5-6)^2 + (-2-1)^2
= √(121 + 3) = √130
and if it was the other way around the length is
√((6--5)^2 + (1- -2)^2)
= √(121 + 9)
= √(130).
The differences are negative in one case and positive in the other but the squares are the same.
