How do you find the ordered pair?
Ordered pairs are often used to represent two variables. When we write (x, y) = (7, – 2), we mean x = 7 and y = – 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.
How do you write an ordered pair of coordinates?
An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.
What is the ordered pair in a coordinate plane?
An ordered pair is also known as a coordinate pair because it consists of x- and y-coordinates. For example, we can represent the point (3,−1) in the plane by moving three units to the right of the origin in the horizontal direction, and one unit down in the vertical direction.
What is an ordered pair in a coordinate grid?
The numbers on a coordinate grid are used to locate points. Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate. Ordered pairs are written in parentheses (x-coordinate, y-coordinate).
What are ordered pair numbers?
An ordered pair is two numbers for which the order in which they are given is important. Ordered pair usually refers to a set of two numbers used to locate a point in a coordinate plane. When an ordered pair refers to the location of a point in the coordinate plane, they are called the coordinates of the point.
What is ordered pair called?
Ordered pair usually refers to a set of two numbers used to locate a point in a coordinate plane. When an ordered pair refers to the location of a point in the coordinate plane, they are called the coordinates of the point.
Why is an ordered pair called a coordinate pair?
An ordered pair is also known as a coordinate pair because it consists of x- and y -coordinates. For example, we can represent the point (3, − 1) in the plane by moving three units to the right of the origin in the horizontal direction, and one unit down in the vertical direction. See (Figure).
How are the quadrants in a Cartesian coordinate system numbered?
The Cartesian coordinate system, also called the rectangular coordinate system, is based on a two-dimensional plane consisting of the x -axis and the y -axis. Perpendicular to each other, the axes divide the plane into four sections. Each section is called a quadrant; the quadrants are numbered counterclockwise as shown in (Figure) Figure 2.
Is the Cartesian coordinate system based on a two dimensional plane?
The Cartesian coordinate system, also called the rectangular coordinate system, is based on a two-dimensional plane consisting of the x -axis and the y -axis. Perpendicular to each other, the axes divide the plane into four sections. Each section is called a quadrant; the quadrants are numbered counterclockwise as shown in (Figure)
How are the axes divided in a coordinate system?
From the origin, each axis is further divided into equal units: increasing, positive numbers to the right on the x- axis and up the y- axis; decreasing, negative numbers to the left on the x- axis and down the y- axis. The axes extend to positive and negative infinity as shown by the arrowheads in (Figure).
