Graphing, Reflections, Distance on Coordinate Plane

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal axis (x-axis) and a vertical axis (y-axis).

Front

What are the coordinates of a point?

Back

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

Front

What does the x-axis represent?

Back

The horizontal axis of the coordinate plane where the y-coordinate is zero.

Front

What does the y-axis represent?

Back

The vertical axis of the coordinate plane where the x-coordinate is zero.

Front

What is an ordered pair?

Back

A pair of numbers used to locate a point on the coordinate plane, written in the form (x, y).

Front

How do you identify the coordinates of a point?

Back

By looking at its position relative to the x-axis and y-axis.

Front

What is reflection in geometry?

Back

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

Front

What is reflection over the x-axis?

Back

A transformation where each point (x, y) is mapped to (x, -y).

Front

What is reflection over the y-axis?

Back

A transformation where each point (x, y) is mapped to (-x, y).

Front

What is the distance formula?

Back

The formula used to determine the distance between two points (x1, y1) and (x2, y2): d = √((x2 - x1)² + (y2 - y1)²).
