## What is the ordered pair for point A?

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. The ordered pair for point A is (3, 1).

## What is the ordered pair for point T?

Which ordered pair corresponds to point T? Point T is 3 units to the right of the origin and 3 units down. So, the x-coordinate is 3 and the y-coordinate is J3. The ordered pair (3, J3) corresponds to point T.

**What is 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.

### What does an ordered pair look like?

Ordered pairs are sets of numbers used for plotting points. They are always written inside parentheses, and are separated by a comma. Ordered pairs are usually seen together with a four-quadrant graph (also called a coordinate plane). This is a grid that looks like graph paper on which two perpendicular lines cross.

### How do you identify points on a graph?

Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first. For example, in the figure we’ve been using, we have identified both the x and y coordinate for each of the points B and D. The x-coordinate of point B is 100.

**Which of the following is an ordered pair?**

Answer: An ordered pair is a pair of numbers in a specific order. For example, (1, 2) and (- 4, 12) are ordered pairs. The order of the two numbers is important: (1, 2) is not equivalent to (2, 1) — (1, 2)≠(2, 1).

#### What ordered pair examples?

An ordered pair is a pair of numbers in a specific order. For example, (1, 2) and (- 4, 12) are ordered pairs. The order of the two numbers is important: (1, 2) is not equivalent to (2, 1) — (1, 2)≠(2, 1).

#### What is the ordered pair of point B?

The ordered pair for point B is (4, -3).

**What is the ordered pair of 0 0 called?**

the origin

The point given by (0,0) is called the origin. If a graph passes through the origin then the x-intercept and the y-intercept are at the same point and are therefore equal. This is the only point where the x- and y- coordinates are equal.

## Is the first 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. From 4 on the x-axis move up to the point and notice the number with which it aligns on the y-axis.
