Coordinate System

What is a coordinate system?

Back

A coordinate system is a method for identifying the position of points in a space using numbers, typically represented as ordered pairs (x, y) in a two-dimensional space.

What does an ordered pair represent in a coordinate system?

Back

An ordered pair represents a specific point in a coordinate system, where the first number indicates the position along the x-axis and the second number indicates the position along the y-axis.

Front

What is the x-axis?

Back

The x-axis is the horizontal line in a coordinate system where the y-coordinate is zero. It is used to measure the horizontal position of points.

Front

What is the y-axis?

Back

The y-axis is the vertical line in a coordinate system where the x-coordinate is zero. It is used to measure the vertical position of points.

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

Back

To identify the coordinates of a point on a grid, find the horizontal position (x-coordinate) first, followed by the vertical position (y-coordinate), written as (x, y).

Front

What is the origin in a coordinate system?

Back

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

Front

If a point has coordinates (3, 4), what does this mean?

Back

This means the point is located 3 units to the right of the origin along the x-axis and 4 units up along the y-axis.

Front

What is the significance of the first number in an ordered pair?

Back

The first number in an ordered pair represents the position along the x-axis.

Front

What is the significance of the second number in an ordered pair?

Back

The second number in an ordered pair represents the position along the y-axis.

Front

How can you determine if a point lies on a specific line?

Back

To determine if a point lies on a specific line, check if the coordinates of the point satisfy the equation of the line.
