Question

The figure below will be translated 4 units up and 3 units to the right. Which of the following represents the coordinates of the transformed figure?

A. A'(6, 9), B'(9, 14), C'(12, 11)
B. A'(8, 10), B'(11, 15), C'(15, 12)
C. A'(9, 9), B'(12, 14), C'(16, 11)
D. A'(9, 10), B'(12, 15), C'(16, 12)

Answer 1

Procedure: add 3 to every x-coordinate and 4 to every y-coordinate.

=> A (5,6) → A' (5 + 3, 6 + 4) = A'(8,10)

=> B(8,11) → B' (8 + 3, 11 + 4) = B'(11,15)

=>C(12,8) → C' (12 + 3, 8 + 4) = C'(15,12)

Answer: B. A'(8, 10), B'(11, 15), C'(15, 12)
