quadrilateral how do I construct the transformation

Question

Given a quadrilateral with the vertices (-8, 9), (-8, 5), (-2, 3), and (-2, 7), construct the transformation of the image (x, y) → (x + 9, y − 5).

Answer 1

(x,y ) → (x + 9. y-5)

A (-8, 9) → (-8 + 9, 9-5) →(1, 4) A'

B (-8, 5) → (-8 +9, 5-5) → (1, 0) B'

C (-2, 3) → (-2 + 9, 3-5) → (7, -2) C'

D (-2, 7)→ (-2 + 9, 7-5) → (7, 2) D'

 

Plot points A', B', C' and D' on the coordinate grid with ABCD to show the transformation.
