When outlining the **coordinates** of a location, the line of latitude is always given first followed by the line of longitude. Therefore, the **coordinates** of this location will be: 10°N latitude, 70°W longitude. The line of latitude is **read** as 41 degrees (41°), 24 minutes (24′), 12.

The **order** in which you write x- and y-**coordinates** in an ordered pair is very important. The x-**coordinate** always comes first, followed by the y-**coordinate**.

## Q. How do you use coordinates to describe position?

When **using coordinates to describe** the location of physical **positions** in the real world, we must always have appropriate units of length for the **coordinates**. For example, the following **coordinates** all specify the same **position**: x=2 mx=6.

## Q. Which comes first latitude or longitude?

When you see a pair of coordinates and can’t remember whether **latitude** or **longitude** comes **first**, think about alphabetical order to remember. **Latitude** comes **first** in alphabetical order and it also is the **first** coordinate in a set. **Longitude** is the second coordinate in the set.

## Q. How do you read out loud coordinates?

third quadrant

## Q. In which quadrant both coordinates of a point are negative?

In Quadrant I, both the x– and y-coordinates are positive; in **Quadrant II**, the x-coordinate is negative, but the y-coordinate is positive; in **Quadrant III** both are negative; and in **Quadrant IV**, x is positive but y is negative.

## Q. In which quadrant do points lie if their abscissa is zero?

Answer. **If** the **abscissa of** a point (x coordinate) **of** a point is **zero**, the point **lies** on the y axis. **When** the **abscissa** is 0, it means that it is at the origin. On the other hand, the **abscissae** on the right and left sides **of** the x axis have positive and negative values respectively.

## Q. In which quadrant abscissa is positive and ordinate is negative?

Explanation: The **abscissa** is the horizontal direction( x ) and the **ordinate** is the vertical direction( y ). The **Quadrants** are numbered in a counter-clockwise direction. As can be seen from the image the IV(4th) **quadrant** is **positive** in x direction and **negative** in the y direction.

## Q. What are the signs of the coordinates in each quadrant?

Signs of x-axis and y-axis in each quadrant In the first quadrant, both **x and y** take positive values. In the second quadrant, x is negative and y is positive. In the third quadrant, **x and y** are negative, and in the fourth quadrant, x is positive and y is negative.

## Q. What quadrant does the point 1/2 lie?

Answer: (-**1**,-**2**)**lies** in Third **Quadrant**.

## Q. What do you call the vertical line of the Cartesian coordinate plane?

The rectangular **coordinate** system is formed by two intersecting perpendicular number **lines**. The **horizontal** number **line** is **called** the x-axis and the **vertical** number **line** is **called** the y-axis.

## Q. On which axis does the point 0 4 lie?

Point (0, 4) lies: in I quadrant. on **x-axis**.
