Coordinate Plane Review (NS.6b, NS.8)

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

What are the coordinates of a point?

Back

An ordered pair (x, y) that defines the position of a point on the coordinate plane, where 'x' is the horizontal distance from the origin and 'y' is the vertical distance.

Front

What is the reflection of a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate to (-x, y).

Front

What is the reflection of a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, change the sign of the y-coordinate to (x, -y).

Front

What is the origin in the coordinate plane?

Back

The point (0, 0) where the x-axis and y-axis intersect.

Front

How do you find the distance between two points on the coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent the coordinates of a point on the coordinate plane.

Front

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

Back

The y-coordinate changes sign, resulting in (x, -y).

Front

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

Back

The x-coordinate changes sign, resulting in (-x, y).

Front

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

Back

The distance is 4 units.
