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). It is used to locate points using ordered pairs (x, y).

Front

What are the x-axis and y-axis?

Back

The x-axis is the horizontal line on a coordinate grid, while the y-axis is the vertical line. Together, they create the framework for plotting points.

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' is the position on the x-axis and 'y' is the position on the y-axis.

Front

How do you plot a point on a coordinate grid?

Back

To plot a point, start at the origin (0, 0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

What is the origin in a coordinate grid?

Back

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

Front

What are quadrants in a coordinate grid?

Back

Quadrants are the four sections of a coordinate grid, created by the x-axis and y-axis. They are labeled as Quadrant I, II, III, and IV, starting from the upper right and moving counterclockwise.

Front

What is the significance of Quadrant I?

Back

Quadrant I contains all points where both x and y coordinates are positive. It is located in the upper right section of the coordinate grid.

Front

What is the significance of Quadrant II?

Back

Quadrant II contains points where x coordinates are negative and y coordinates are positive. It is located in the upper left section of the coordinate grid.

Front

What is the significance of Quadrant III?

Back

Quadrant III contains points where both x and y coordinates are negative. It is located in the lower left section of the coordinate grid.

Front

What is the significance of Quadrant IV?

Back

Quadrant IV contains points where x coordinates are positive and y coordinates are negative. It is located in the lower right section of the coordinate grid.
