See a 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)(-6) - color(blue)(-3))^2 + (color(red)(-4) - color(blue)(-5))^2)

d = sqrt((color(red)(-6) + color(blue)(3))^2 + (color(red)(-4) + color(blue)(5))^2)

d = sqrt((-3)^2 + 1^2)

d = sqrt(9 + 1)

d = sqrt(10)

Or

d = 3.162 rounded to the nearest thousandth
