Question

PLEASE PLEASE PLEASE HELP ME!!!!!!!!!

Choose the algebraic description that maps the image ΔXYZ onto ΔX′Y′Z′. Question options: A)
(x, y) → (x + 6, y – 1)
B)
(x, y) → (x – 5, y – 1)
C)
(x, y) → (x + 5, y – 1)
D)
(x, y) → (x – 6, y – 1)

Answer 1

D

Explanation:

To get from ΔXYZ (the figure on the right) to ΔX′Y′Z′ (the figure on the left), each point is translated left 6 units and down 1.

Movement left and right is related to the x-axis. So moving 6 units left (in a negative direction) is x - 6.

Movement up and down is related to the y-axis. So going down (in the negative direction) is y - 1.
