Question

Which equation set up would we use to find the Length of PR if P is located at (-6,4) and R is located at (-8,6)

Answer 1

2)

Given,

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

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

The length of PR is,

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

Substituting the values then,

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

Hence, option B is correct.
