Question 30 • Mathematical Models with Applications - MA4072 CR

Triangle XYZ with vertices X(5, 4), Y(3, -1) and Z(0, 2) is translated so that X’ is at (3, 1). Choose the coordinates of Y’ and Z’.

Answer
A
Y’(5, 2) and Z’(2, 5)
B
Y’(0, -3) and Z’(-3, 0)
C
Y’(1, -4) and Z’(-2, -1)
D
Y’(11, 4) and Z’(8, 6)

Explanation

To move X(5, 4) to X′(3, 1), translate every point by (3 − 5, 1 − 4) = (−2, −3). Apply this same shift to Y(3, −1) and Z(0, 2): Y′ = (1, −4) and Z′ = (−2, −1). These coordinates match choice c.
