$d=13$

The distance formula is $d=sqrt((y_2-y_1)^2 + (x_2-x_1)^2)$

$(8,2) and (-5,2)$

$x_1 = 8$
$y_1 = 2$
$x_2 = -5$
$y_2 = 2$

$d=sqrt((y_2-y_1)^2 + (x_2-x_1)^2)$
$d=sqrt((2-2)^2 + (-5-8))^2)$
$d=sqrt((0)^2 + (-13)^2)$
$d=sqrt(0 + 169)$
$d=sqrt(169)$
$d=13$

What is the distance between (8, 2) (8, 2) and (-5,2 ) (-5,2 ) ?
