See the entire solution process below:

Explanation:

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)(9) - color(blue)(1))^2 + (color(red)(1) - color(blue)(6))^2)#

#d = sqrt(8^2 + (-5)^2)#

#d = sqrt(64 + 25)#

#d = sqrt(89) = 9.434# rounded to the nearest thousandth
