The distance between the points is #5#

The formula for calculating the distance between two points is:

#color(red)(d = sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2))#

Substituting our points into the formula givesL

#d = sqrt((-1 - 2)^2 + (-5 - -1)^2)#

#d = sqrt((-3)^2 + (-4)^2)#

#d = sqrt(9 + 16)#

#d = sqrt(25)#

#d = 5#
