Reflections and distance on the Coordinate Plane

Front

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

Back

The reflection of a point (x, y) over the x-axis is (x, -y).

Front

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

Back

The reflection of a point (x, y) over the y-axis is (-x, y).

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the reflection of C (0,-4) over the x-axis?

Back

C' (0, 4).

Front

What is the reflection of D (4, 3) over the y-axis?

Back

D' (-4, 3).

Front

What does a reflection over the x-axis do to the y-coordinate?

Back

It changes the sign of the y-coordinate.

Front

What does a reflection over the y-axis do to the x-coordinate?

Back

It changes the sign of the x-coordinate.

Front

If the point P (2, 5) is reflected over the x-axis, what is the new point?

Back

P' (2, -5).

Front

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

Back

Q' (3, -2).

Front

What is the distance between the points (1, 2) and (5, 6)?

Back

The distance is 4.
