See the process for using the distance formula 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 points from the problem gives:

$d = sqrt((color(red)(0) - color(blue)(-1))^2 + (color(red)(-5) - color(blue)(1))^2)$

We can now calculate the difference:

$d = sqrt((1)^2 + (-6)^2)$

$d = sqrt(1 + 36)$

$d = sqrt(37)$

$d = 6.08$ rounded to the nearest hundredth.
