$d = sqrt(73)$

or

$d = 8.544$ rounded to the nearest thousandth

The formula for calculating the distance between two points is:

$color(red)(d = sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2))$

Substituting the two points we are given in this problem gives us:

$d = sqrt((-2 - -5)^2 + (-6 - 2)^2)$

$d = sqrt((-2 + 5)^2 + (-6 - 2)^2)$

$d = sqrt((3)^2 + (-8)^2)$

$d = sqrt(9 + 64)$

$d = sqrt(73)$

$d = 8.544$
