Problem
(7) Line segment \( \overline{R S} \) is shown below with coordinates \( R(-8,-3) \) and \( S(3,-3) \). Which coordinate below would represent \( R^{\prime} \) if point \( R \) was reflected across the \( x \) axis? (A) \( (-8,3) \) (B) \( (3,3) \) (C) \( (8,-3) \) (D) \( (-3,-3) \)
Solution
Step 1 ：R(-8,-3)
Step 2 ：Reflect R across x-axis
Step 3 ：R'(-8,3)
