6th Grade - Unit 3B Review

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. For example, |-5| = 5.

Front

What does the coordinate (1, 2) represent on a graph?

Back

The coordinate (1, 2) represents a point that is 1 unit to the right and 2 units up from the origin (0, 0) on a Cartesian plane.

Front

What is the opposite of a number?

Back

The opposite of a number is the number that is the same distance from zero but in the opposite direction. For example, the opposite of -3 is 3.

Front

How do you find the distance between two points on a graph?

Back

To find the distance between two points (x1, y1) and (x2, y2), use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

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).

Front

What does the term 'coordinate' mean?

Back

A coordinate is a set of values that show an exact position on a graph, usually represented as (x, y).

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0). It is the starting point for measuring coordinates.

Front

What is the distance from Point A (2, 3) to Point B (2, 7)?

Back

The distance from Point A to Point B is 4 units, calculated as |7 - 3|.

Front

What is the absolute value of |-12|?

Back

The absolute value of |-12| is 12.

Front

If Point C is at (3, 4) and Point D is at (3, 1), what is the distance between them?

Back

The distance between Point C and Point D is 3 units, calculated as |4 - 1|.
