Coordinate Grids

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). It is 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 is the horizontal position and y is the vertical position.

Front

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

Back

The origin is the point where the x-axis and y-axis intersect, representing the coordinates (0,0). It is the starting point for measuring distances on the grid.

Front

How do you move right on a coordinate grid?

Back

To move right on a coordinate grid, you increase the x-coordinate of the ordered pair.

Front

How do you move up on a coordinate grid?

Back

To move up on a coordinate grid, you increase the y-coordinate of the ordered pair.

Front

What does it mean to have the same x-coordinate?

Back

Having the same x-coordinate means that two points are vertically aligned on the coordinate grid, meaning they share the same horizontal position.

Front

What does it mean to have the same y-coordinate?

Back

Having the same y-coordinate means that two points are horizontally aligned on the coordinate grid, meaning they share the same vertical position.

Front

How do you locate a point using ordered pairs?

Back

To locate a point using ordered pairs, start at the origin (0,0), move horizontally to the x-coordinate, and then move vertically to the y-coordinate.

Front

What is the x-axis?

Back

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

Front

What is the y-axis?

Back

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