Answer:

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)(-4) - color(blue)(-10))^2 + (color(red)(-6) - color(blue)(2))^2)#

#d = sqrt((color(red)(-4) + color(blue)(10))^2 + (color(red)(-6) - color(blue)(2))^2)#

#d = sqrt(6^2 + (-8)^2)#

#d = sqrt(36 + 64)#

#d = sqrt(100) = 10#
