y-axis?
с

Answer 1

Answer:

• (2, -4)

Step-by-step explanation:

The rule for the reflection across the y-axis:

• (x, y) → (-x, y)

Coordinates of B is (-2, -4)

New coordinates of B:

• (-2, -4) → (2, -4)

Answer 2

Rule

(x,y)=(-x,y)

So

Old coordinate is (-2,-4)

New one

• (-(-2),-4)
• (2,-4)
