△XYZ has vertices X(15,−8), Y(13, 21), and Z(−17, 17). Which of the following represents the translation of △XYZ along vector <−6, 5> and its reflection across the x-axis?
Please help!
Answers:
X (15, −8) → X ′(9, −3) → X ″(9, 3);
Y (13, 21) → Y ′(7, 26) → Y ″(7, −26);
Z (−17, 17) → Z ′(−23, 22) → Z ″(−23, −22)

X (15, −8) → X ′(21, −13) → X ″(−21, 13);
Y (13, 21) → Y ′(18, 12) → Y ″(−18, 12);
Z (−17, 17) → Z ′(−11, 12) → Z ″(11, 12)

X (15, −8) → X ′(21, −13) → X ″(21, 13);
Y (13, 21) → Y ′(18, 12)→ Y ″(18, −12);
Z (−17, 17)→ Z ′(−11, 12)→ Z ″(−11, −12)

X (15, −8) → X ′(9, −3) → X ″(−9, −3);
Y (13, 21) → Y ′(7, 26) → Y ″(−7, 26);
Z (−17, 17)→ Z ′(−23, 23)→ Z ″(23, 23)
