Answer:

Step-by-step explanation:

The triangle is being reflected over the y-axis.

  • The rule for a reflection over the y-axis is (x, y) → (x, -y)
  • This means that the x-values stay the same while the y-values change.

A(x, y) → (x, -y)

A(1, 4) → (1, -4)

A'(1, -4)

B(x, y) → (x, -y)

B(4, 3) → (4, -3)

B'(4, -3)

C(x, y) → (x, -y)

C(2, 1) → (2, -1)

C'(2, -1)

Hope this helps!
