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

Explanation:

Using the Pythagorean Theorem:

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

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