## How do you number quadrants?

The first **number** in an ordered pair is the x-coordinate. The second **number** is the y-coordinate. The coordinate axes divide the plane into four regions called **quadrants**. The **quadrants** are numbered I, II, III, and IV as shown on the grid below.

## What are the 4 quadrants on a coordinate plane?

**Quadrant** one (QI) is the top right fourth of the **coordinate plane**, where there are only positive **coordinates**. **Quadrant** two (QII) is the top left fourth of the **coordinate plane**. **Quadrant** three (QIII) is the bottom left fourth. **Quadrant four** (QIV) is the bottom right fourth.

## How do you read quadrants?

The first **quadrant** is the upper right-hand corner of the graph, the section where both x and y are positive. The second **quadrant**, in the upper left-hand corner, includes negative values of x and positive values of y. The third **quadrant**, the lower left-hand corner, includes negative values of both x and y.

## Why is counter clockwise positive?

And we assign the **positive** direction of the x axis from left to right and the the **positive** direction of the y axis from down to up. So it is more simple to assign the **positive** direction to an angle if it rotate the **positive** x semi-axis toward the **positive** y semi-axis and this is the **counter clockwise** direction.

## In which quadrant is the point 17 18?

**Point** (**17**, **18**) is **located** in **Quadrant** I, because both the x and y axis are positive numbers.

## What are the 4 quadrants?

The **Four** Abdominal **Quadrants** The **four quadrants** are easy to remember because they consist of a left upper **quadrant** (LUQ), left lower **quadrant** (LLQ), right upper **quadrant** (RUQ), and right lower **quadrant** (RLQ).

## In which quadrant does the point 13 18 Lie?

Quadrant 1

## What does quadrant mean?

A **quadrant is** one of four equal parts into which a circle or other shape has been divided.

## What is the best definition for quadrant?

1 : one-fourth of a circle. 2 : any of the four parts into which something is divided by two imaginary or real lines that intersect each other at right angles. **quadrant**.

## What is a quadrant used for?

A **quadrant** is an instrument that is **used to** measure angles up to 90°. Different versions of this instrument could be **used to** calculate various readings, such as longitude, latitude, and time of day. It was originally proposed by Ptolemy as a better kind of astrolabe.

## Where do the four quadrants meet?

The number plane, or Cartesian plane, is divided into **four quadrants** by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin.

## What quadrant does the angle lie?

**Quadrants** & Quadrantal **Angles** **Angles** between 0∘ and 90∘ are in the first **quadrant**. **Angles** between 90∘ and 180∘ are in the second **quadrant**. **Angles** between 180∘ and 270∘ are in the third **quadrant**. **Angles** between 270∘ and 360∘ are in the fourth **quadrant**.

## Where do the I and II quadrant meet?

The point (-**2**, 4) lies in the **II quadrant**. The point (3, -1) lies in the IV **quadrant**. The point (-1, 0) lies on the negative x-axis. The point (1, **2**) lies in the I **quadrant**.

## What is the third quadrant?

**Quadrant** III is the **third quadrant**. It is located on the lower left side of the plane. All points plotted in the **third quadrant** have both negative x-coordinates and negative y-coordinates. **Quadrant** IV is the fourth **quadrant**.

## Why is cosine positive in the fourth quadrant?

For an angle in the second **quadrant** the point P has negative x coordinate and **positive** y coordinate. ... For an angle in the **fourth quadrant** the point P has **positive** x coordinate and negative y coordinate. Therefore: In **Quadrant** IV, **cos**(θ) > 0, **sin**(θ) < 0 and tan(θ) < 0 (**Cosine positive**).

## In which quadrant does the point (- 5 0 lie?

We can see that the co-ordinate (**5**,**0**) **lies** in the first **quadrant** as both abscissa and ordinate of the **point** are positive.

## Which quadrant is 9/2 located?

The point is **located** in the fourth **quadrant** because x is positive and y is negative. The **quadrants** are labeled in counter-clockwise order, starting in the upper-right.

## Which quadrant contains the point named 2 5?

1 Answer. Daniel L. This **point** lies in the fourth **quadrant**.

## In which quadrant is the point 0 4?

The correct answer is d. **Quadrant** IV. From the origin move 1 unit right and **4** units down, the **point** is in **Quadrant** IV.

## In which quadrant is the following point (- 3 12?

second quadrant

## What quadrant is it in if it on the line?

**If** only the first coordinate is positive, then the point is in **quadrant** 4. **If** only the second coordinate is positive, then the point is in **quadrant** 2. **If** both coordinates are negative, the point is located in **quadrant** 3. **If** one coordinate is zero, then the point is located on the x-axis or the y-axis.

## What is the quadrant of 0?

The point (**0**,**0**) doesn't lie in a specific **quadrant**. This is because it's essentially where the two axes (x and y) meet; the boundary between all 4 **quadrants**. It's known as the origin, and not really defined as belonging to any of the **quadrants** on a coordinate plane.

## What are the coordinates of point C?

2 Answers By Expert Tutors Since the ratio is 5:4, the x **coordinate of point c** is 5/9 of the way between the x **coordinates of points** A and B: -4 and -5, which is -4.

## What do you call 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.

## What are the coordinates of point D?

The **coordinates of point D** are (7, 4) and the **coordinates of point** E are (1, −3) .

## How do you find C in coordinate geometry?

where m, the gradient, is the height through which the line rises in one unit step in the horizontal direction, and **c**, the intercept, is the y-**coordinate** of the point of intersection between the line and the y-axis.

## What is coordinate formula?

The slope of a line AB having **coordinates** A(x1, y1) and B(x2, y2) is given as. m = t a n θ = y 2 − y 1 x 2 − x 1 m=tan\theta =\frac {y_2-y_1}{x_2-x_1} m=tanθ=x2−x1y2−y1. Note: Slope of X-axis is 0 and the slope of Y-axis is not defined.

## What is the formula for coordinates?

To **calculate** it: Add both "x" **coordinates**, divide by 2. Add both "y" **coordinates**, divide by 2.

## What is coordinate geometry formula?

In **coordinate geometry**, **Section formula** is used to find the ratio in which a line segment is divided by a point internally or externally. It is used to find out the centroid, incenter and excenters of a triangle. In physics, it is used to find the center of mass of systems, equilibrium points, etc.
