Question

what is the distance formula? 6/10 d = sqrt((x2 - x1)^2 + (y2 - y1)^2) d = (x2 - x1)^2 + (y2 - y1)^2 d = sqrt((x2 - x1)^2+(y2 - y1)) d = sqrt((y2 - y1)+(x2 - x1))

Explanation:

Step1: Recall distance formula

The distance $d$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ in a two - dimensional plane is given by taking the square root of the sum of the square of the difference in $x$ - coordinates and the square of the difference in $y$ - coordinates.
$d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$

Answer:

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