Topic 14: Coordinate Grid

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 (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).

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 does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, indicating the horizontal position on the grid.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, indicating the vertical position on the grid.

Front

If a point is located at (3, 2), where is it on the grid?

Back

The point (3, 2) is located 3 units to the right of the origin and 2 units up.

Front

What is the distance between the points (1, 1) and (1, 4)?

Back

The distance is 3 units, as they are on the same vertical line.

Front

What is the distance between the points (2, 3) and (5, 3)?

Back

The distance is 3 units, as they are on the same horizontal line.
