The distance between $P(x_1, y_1)$ and $Q(x_2, y_2)$ is —

Question

Accepted Answer

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

Answer

$\sqrt{(x_2+x_1)^2+(y_2+y_1)^2}$

Answer

$(x_2-x_1)^2+(y_2-y_1)^2$

Answer

$|x_2-x_1|+|y_2-y_1|$

The distance between P(x1,y1)P(x_1, y_1)P(x1​,y1​) and Q(x2,y2)Q(x_2, y_2)Q(x2​,y2​) is —
