Which of the following is the correct formula for finding distance (d) between two points (x1, y1) and (x2, y2)?

d = (x 2 -x 1 ) 2 + (y 2 -y 1 ) 2

Which of the following is the correct formula for finding distance (d)

1.	Which of the following is the correct formula for finding distance (d) between two points (x₁, y₁) and (x₂, y₂)?
A.	d<sup>2</sup> = (x<sub>2</sub>-x<sub>1</sub>)<sup>2</sup> + (y<sub>2</sub>-y<sub>1</sub>)<sup>2</sup>
B.	d<sup>4</sup> = (x<sub>2</sub>-x<sub>1</sub>)<sup>2</sup> + (y<sub>2</sub>-y<sub>1</sub>)<sup>2</sup>
C.	d<sup>3</sup> = (x<sub>2</sub>-x<sub>1</sub>)<sup>2</sup> + (y<sub>2</sub>-y<sub>1</sub>)<sup>2</sup>
D.	d = (x<sub>2</sub>-x<sub>1</sub>)<sup>2</sup> + (y<sub>2</sub>-y<sub>1</sub>) <sup>2</sup>
Answer» D. d = (x<sub>2</sub>-x<sub>1</sub>)<sup>2</sup> + (y<sub>2</sub>-y<sub>1</sub>) <sup>2</sup>
