Back

A point on a coordinate plane, represented as (x, y).

Front

Which points are reflections of each other? (Think a mirror)

Front

What is an integer?

Back

A whole number that can be positive, negative, or zero.

Front

Front

What is the absolute value of a number?

Back

The distance of that number from zero on the number line, always positive.

Front

What does it mean for two points to be equidistant?

Back

They are the same distance from a specific point or line.
