See the entire solution process below:

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 values from the points in the problem gives:

$d = sqrt((color(red)(-12) - color(blue)(7))^2 + (color(red)(-1) - color(blue)(5))^2)$

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

$d = sqrt(361 + 36)$

$d = sqrt(397) = 19.925$ Rounded to the nearest hundredth.
