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:

$d = sqrt((color(red)(9) - color(blue)(1))^2 + (color(red)(1) - color(blue)(6))^2)$

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

$d = sqrt(64 + 25)$

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

What is the distance between (1, 6) (1, 6) and (9,1)(9,1)?
