Use the distance formula to solve this problem. See full 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 two points from the problem gives:

#d = sqrt((color(red)(-2) - color(blue)(7))^2 + (color(red)(6) - color(blue)(-1))^2)#

#d = sqrt((color(red)(-2) - color(blue)(7))^2 + (color(red)(6) + color(blue)(1))^2)#

#d = sqrt((-9)^2 + (7)^2)#

#d = sqrt(81 + 49)#

#d = sqrt(130)#

#d = 11.4#
