The distance between the points is $5$

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 our points into the formula givesL

$d = sqrt((-1 - 2)^2 + (-5 - -1)^2)$

$d = sqrt((-3)^2 + (-4)^2)$

$d = sqrt(9 + 16)$

$d = sqrt(25)$

$d = 5$
