Find the length between the points A(4, 2) and B(–3, 5)

Question

Find the length between the points A(4, 2) and B(–3, 5).

Answer 1

The distance may be obtained by doing: D^2 = (X2-X1)^2 + (Y2-Y1)^2; then,

X2=-3; X1= 4; Y2 =5; Y1 =2

Equating all this numbers we have: D^2= (-7)^2 + (3)^2 = 49 + 9 = 58

D= 7.62 units.

I used the Pythagorean Theorem.
