Problem
(8) If parallelogram \( A B C D \) is translated left 2 units and down 5 units, what is the resulting coordinate of \( B^{\prime} \) ? (A) \( (10,2) \) (B) \( (8,2) \) (C) \( (6,7) \) (D) \( (6,2) \) (c) 2019 The Math Café
Solution
Step 1 ：Translate left 2 units: \( B_x^{\prime} = B_x - 2 \)
Step 2 ：Translate down 5 units: \( B_y^{\prime} = B_y - 5 \)
Step 3 ：Calculate new coordinates: \( B^{\prime} = (6,2) \)
