Front

What are integers?

Back

Integers are whole numbers that can be positive, negative, or zero.

Front

What is the coordinate plane?

Back

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

Front

What is the absolute value of a number?

Back

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

Front

Front

What is the y-axis?

Back

The y-axis is the vertical line on the coordinate plane.

Front

What is the x-axis?
