Question

Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7). Which of the following expressions will he use?

Answer 1

My answer choices are:
A. \[\sqrt{(7-1)^2+(4-3)^2}\]
B. \[\sqrt{(7-3)^2+(4-1)^2}\]
C. \[\sqrt{(7-4)^2+(3-1)^2}\]
D. \[\sqrt{(4-7)^2+(1-3)^2}\]

Answer 2

But I did it myself and I got \[\sqrt{(4-3)^2+(7-1)^2}\]
