Reflections

Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

(x, -y)

Front

What is the result of reflecting a point (x, y) over the y-axis?

Back

(-x, y)

Front

How do you reflect a point across the line y = x?

Back

Swap the coordinates: (x, y) becomes (y, x)

Front

What are the coordinates of point A(5, 2) after reflecting over the x-axis?

Back

A'(5, -2)

Front

If point A(5, 2) is reflected over the y-axis, what are the new coordinates?

Back

A'(-5, 2)

Front

What is the general formula for reflecting a point (x, y) across the line y = -x?

Back

(-y, -x)

Front

What happens to the x-coordinate of a point when it is reflected over the y-axis?

Back

The x-coordinate changes sign.

Front

What happens to the y-coordinate of a point when it is reflected over the x-axis?

Back

The y-coordinate changes sign.

Front

If point C(3, 2) is reflected over the y-axis, what are the new coordinates?

Back

C'(-3, 2)

Front

What are the coordinates of point (2, -4) after reflecting over the y-axis?

Back

(-2, -4)
