I need help plz answer fast

Answer 1

Answer:

Reflecting a point across the y-axis -> changes the sign of the x-coordinate

Reflecting a point across both axes -> changes the sign of both coordinates

Reflecting a point across the x-axis -> changes the sign of the y-coordinate

Step-by-step explanation:

Reflections:

1. The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
2. Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
3. Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.
