$= sqrt (220)$

The coordinates are:
$(8,2) = color(blue)(x_1 , y_1$

$(-5, -9) = color(blue)(x_2 , y_2$

The distance is calculated using formulaa:
Distance $= sqrt ((x_2 - x_1)^2 + ( y_2 - y_1)^2$

$= sqrt ((-5-8)^2 + (-9-2)^2$

$= sqrt ((-13)^2 + (-11)^2$

$= sqrt ((169 + 121)$

$= sqrt (220)$

What is the distance between (8, 2) (8, 2) and (–5, –9) (–5, –9) ?
