What is the second number in an ordered pair it tells the distance to move up or down from the origin?
The second number tells how far to move up (positive) or down (negative) from the x-axis. The numbers in an ordered pair are called coordinates. The first number is called the x-coordinate and the second number is called the y-coordinate. The coordinates for the origin in (0, 0).
What do you call the 2nd number in an ordered pair?
In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate. Note that the x-coordinate is listed before the y-coordinate. This number is the y-coordinate, the second number in the ordered pair.
What is the second number or coordinate in an ordered pair?
y-coordinate
A relation is a set of ordered pairs. The first coordinate (usually the x-coordinate) is called the domain and the second (usually the y-coordinate) is called the range.
What is the ordered pair for the origin?
0, 0
The ordered pair for the origin is (0, 0). The x-coordinate tells how many units from the origin the point is on the x-axis. It is the first number in the ordered pair. The y-coordinate tells how many units from the origin the point is on the y-axis.
How do you solve for ordered pairs?
To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
What is ordered pair in set theory?
The pair of elements that occur in a particular order and are enclosed in brackets is known as a set of ordered pairs. If ‘a’ and ‘b’ are two elements, then the two different pairs are (a, b), (b, a). In an ordered pair (a, b), a is called the first element and b is called the second element.
What’s the first number in an ordered pair called?
x-coordinate
Think How do we distinguish between the two number lines? Circle all of the numbers on the x-axis. Box all of the numbers on the y-axis. An ordered pair is a pair of numbers that describes the location of a point in the coordinate plane. The first number is called the x-coordinate.
How do you solve ordered pairs?
What letter symbolizes the first number in an ordered pair?
The x-coordinate tells how many units from the origin the point is on the x-axis. It is the first number in the ordered pair. The y-coordinate tells how many units from the origin the point is on the y-axis. It is the second number in the ordered pair.
