See a 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:

$d = sqrt((color(red)(3) - color(blue)(6))^2 + (color(red)(4) - color(blue)(8))^2)$

$d = sqrt((-3)^2 + (-4)^2)$

$d = sqrt(9 + 16)$

$d = sqrt(25)$

$d = 5$
