Lesson 2: Coordinate plane word problems# Coordinate plane: FAQ

Frequently asked questions about the coordinate plane.

## What is the coordinate plane?

The coordinate plane is a two-dimensional grid that is used to graph points and lines. A coordinate plane has four sections called quadrants.

Quadrant one (QI) is in the upper right-hand corner of the coordinate plane, Quadrant two (QII) is in the upper left-hand corner, Quadrant three (QIII) is in the lower left-hand corner, and Quadrant four (QIV) is in the lower right-hand corner.

## What are coordinates and what do they represent?

Coordinates are two numbers that are used to locate a point on the coordinate plane.

The first number, or $x$ -coordinate, tells us how far left or right to move from the origin (the point where the two axes intersect). The second number, or $y$ -coordinate, tells us how far up or down to move from the origin.

## How do we graph a point on the coordinate plane?

To graph a point, we first find the x-coordinate on the horizontal axis, and then we find the y-coordinate on the vertical axis. We plot the point where the two lines intersect.

## Where do we use the coordinate plane in the real world?

The coordinate plane is used in many different fields, such as engineering, architecture, and physics.

**bold**Ya supa easy XD(6 votes)

- This is honestly my favorite unit so far. I feel like there's something to do in it.(21 votes)
- is x first or y first?(11 votes)
- the x-coordinate is first(22 votes)

- I love math soooooo much!(13 votes)
- Me too, math is so LOGICAL, unlike people.I wish peoples were logical like math,too.(3 votes)

- this is very easy wow yayyy(13 votes)
- Why is it called the x-axis and the y-axis? Can't it just be called the z-axis or the prime axis? Do the x and y stand for a word?(8 votes)
- the reason is because X And Y are most common to use(6 votes)

- Bro im learing y= 2x over here yall lucky-(9 votes)
- i learned that stuff myself 2 years ago

not too hard in my opion well once you undersand of course(3 votes)
