Triangle XYZ is shown on the coordinate plane.

Triangle XYZ on the coordinate plane with ordered pairs at X 4, 5, at Y 5, 3, at Z 1, 3

If triangle XYZ is translated using the rule (x, y) → (x + 1, y − 4) and then reflected across the y-axis to create triangle X″Y″Z″, what is the location of Z″?

(−2, −1)
(−5, 1)
(−6, −1)
(2, 1)

Respuesta :

Answer: The answer is (-2,-1)

Step-by-step explanation: The reason why it's (-2,-1) is because when you reflect over the y-axis the  you would have this (-x,y) and when you substitute the numbers you get (2,-1) and with the reflection of the y-axis the x should be negative!

Hope this helps
