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:
The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
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.
Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.
