The length of the line segment between Q(5,3) and R(2,-1) is 5

Explanation:

Using the Pythagorean Theorem:

The horizontal distance (i.e. the x distance) between Q and R is
color(white)("XXXX") 5-2 = 3
The vertical distance (i.e. the y distance) between Q and R is
color(white)("XXXX")3- (-1) = 4

The distance between Q and R (as given by the Pythagorean Theorem) is
color(white)("XXXX")sqrt(3^2+4^2) = 5
