Answer:

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)(5) - color(blue)(2))^2 + (color(red)(-4) - color(blue)(-3))^2)#

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

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

#d = sqrt(9 + 1)#

#d = sqrt(10)#

Or

#d = 3.162# rounded to the nearest thousandth.
