Reflections and Distance in the Coordinate plane

Front

What is the reflection of Point A (3, 5) over the x-axis?

Back

A'(3, -5)

Front

When you reflect a point over the x-axis, which coordinate changes to its opposite?

Back

The y-coordinate.

Front

What is the distance between the points (5, 6) and (5, 8)?

Back

2 units

Front

Find the distance between the points (0, 6) and (0, -4).

Back

10 units

Front

What is the distance between the points (3, -5) and (3, -8)?

Back

3 units

Front

Define reflection in the coordinate plane.

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What happens to the x-coordinate when reflecting over the y-axis?

Back

The x-coordinate changes to its opposite.

Front

If Point B (4, 2) is reflected over the y-axis, what is the new point?

Back

B'(-4, 2)

Front

What is the distance between the points (1, 1) and (4, 5)?

Back

5 units
