Graphing, Reflections, Distance on Coordinate Plane

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 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

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What are the coordinates of the origin in a coordinate plane?

Back

The coordinates of the origin are (0, 0).

Front

How many quadrants are in a coordinate plane?

Back

There are 4 quadrants in a coordinate plane.

Front

What is the distance between the points (1, 2) and (4, 6)?

Back

Distance = 5.

Front

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

Back

The reflection is (3, 2).

Front

What is the reflection of the point (-4, 5) over the y-axis?

Back

The reflection is (4, 5).

Front

Which letter corresponds to the coordinate (0, -6)?

Back

The letter O corresponds to the coordinate (0, -6).

Front

What is the distance between the points (-1, -1) and (2, 3)?

Back

Distance = √((2 - (-1))² + (3 - (-1))²) = √(3² + 4²) = 5.
