distance $d=2sqrt101$

$d=20.09975$

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

Given two points: $(15, -10)$ and $(-5, -12)$

Let $P_2(15, -10)$ and $P_1(-5, -12)$

so that $x_2=15$ and $y_2=-10$

also $x_1=-5$ and $y_1=-12$

Direct substitution to the formula:

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

$d=sqrt((15--5)^2+(-10--12)^2)$

$d=sqrt((15+5)^2+(-10+12)^2)$

$d=sqrt((20)^2+(2)^2)$

$d=sqrt(400+4)$

$d=sqrt(404)$

$d=2sqrt101$

$d=20.09975$
