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

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)
The formula of a distance between two points:
[tex]\boxed{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]
