State the formula for the distance between points (x1,y1)(x_1, y_1)(x1,y1) and (x2,y2)(x_2, y_2)(x2,y2).
A
(x2−x1)2+(y2−y1)2
\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
(x2−x1)2+(y2−y1)2
B
(x2+x1)2+(y2+y1)2
\sqrt{(x_2+x_1)^2+(y_2+y_1)^2}
(x2+x1)2+(y2+y1)2
C
(x2−x1)2−(y2−y1)2
\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}
(x2−x1)2−(y2−y1)2
D
(x2−x1)2+(y2−y1)2
(x_2-x_1)^2+(y_2-y_1)^2
(x2−x1)2+(y2−y1)2
