When you flip or mirror an object across a line.

Front

What is the mirror line for a reflection?

Back

The line across which a figure is reflected.

Front

Reflect Point C (2, 3) over the y-axis. What is the new coordinate?

Back

(-2, 3)

Front

What axis is the triangle being reflected over if it is reflected over the line y = -4?

Back

Y-axis

Front

What is the mirror line for the reflection of a point across the line y = x?

Back

y = x

Front

If a point (x, y) is reflected over the x-axis, what is the new coordinate?

Back

(x, -y)

Front

If a point (x, y) is reflected over the y-axis, what is the new coordinate?

Back

(-x, y)

Front

What is the equation of the line that reflects points across the line y = -4?

Back

y = -4

Front

What happens to the coordinates of a point when it is reflected over the line y = x?

Back

The coordinates switch places: (x, y) becomes (y, x).

Front

What is the result of reflecting the point (3, -2) over the x-axis?

Back

(3, 2)
