Given,

The coodinates of point P is (-6,4).

The coordinates of point R is (-8,6).

The length of PR is,

[tex]PR=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substituting the values then,

[tex]\begin{gathered} PR=\sqrt[]{(-8-(-4))^2+(6-4)^2} \\ PR=\sqrt[]{(-8+4)^2+(6-4)^2} \end{gathered}[/tex]

Hence, option B is correct.
