What is absolute value?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, the absolute value of -20 is 20.

What does the x-axis represent in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero. Points on this axis have the form (x, 0).

What does the y-axis represent in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero. Points on this axis have the form (0, y).

What is a coordinate plane?

Back

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

What is an ordered pair?

Back

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

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0, 0).

What does it mean for points to be reflected across the x-axis?

Back

When points are reflected across the x-axis, their y-coordinates change sign, while their x-coordinates remain the same.

What is the relationship between two points that are reflections of each other across the origin?

Back

Two points are reflections across the origin if their coordinates are opposite in sign, such as (x, y) and (-x, -y).

Front

What is the relationship between two points that are reflections across both the x-axis and y-axis?

Back

Two points are reflections across both axes if their coordinates are opposite in sign, such as (x, y) and (-x, -y).
