The distance is $sqrt(397)$ or 19.9 rounded to the nearest tenth.

The origin is point (0, 0).
The formula for calculating the distance between two points is:

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

Substituting the point given in the problem and the origin gives:

$d = sqrt((color(red)(0) - color(blue)(-19))^2 + (color(red)(0) - color(blue)(6))^2)$

$d = sqrt((color(red)(0) + color(blue)(19))^2 + (color(red)(0) - color(blue)(6))^2)$

$d = sqrt(19^2 + (-6)^2)$

$d = sqrt(361 + 36)$

$d = sqrt(397) = 19.9$ rounded to the nearest tenth.
