COORDINATE GRID REVIEW

Front

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate grid, written in the form (x, y), where x represents the horizontal position and y represents the vertical position.

Front

What does the point (0, 0) represent on a coordinate grid?

Back

The point (0, 0) is known as the origin, where the x-axis and y-axis intersect.

Front

How do you plot the point (4, -12) on a coordinate grid?

Back

To plot (4, -12), start at the origin (0, 0), move right 4 units along the x-axis, and then move down 12 units along the y-axis.

Front

What are the four quadrants of a coordinate grid?

Back

The four quadrants are: Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

Which quadrant contains the point (2, 5)?

Back

Quadrant I, where both x and y are positive.

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a coordinate grid where the y-coordinate is 0.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a coordinate grid where the x-coordinate is 0.

Front

How do you identify the coordinates of a point on a grid?

Back

The coordinates of a point are identified by its position relative to the x-axis and y-axis, expressed as (x, y).

Front

What is the significance of the signs in an ordered pair?

Back

The signs indicate the direction of movement from the origin: positive x means right, negative x means left, positive y means up, and negative y means down.
