Question

Which of the following is the correct form of the distance formula?

Answer 1

Answer:

A d = sqrt( (x2-x1)^2 + (y2-y1)^2)

Step-by-step explanation:

The distance formula between two points is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

Answer 2

The formula of a distance between two points:

$\boxed{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}$
