Lesson 1: Intro to the coordinate plane# Graph points review (positive numbers only)

Review graphing points and identifying points on quadrant I of a coordinate plane. Then, try some practice problems.

### Graphing points in the coordinate plane

Points in the coordinate plane are identified by coordinates given in the form left parenthesis, start color #11accd, x, end color #11accd, comma, start color #1fab54, y, end color #1fab54, right parenthesis.

The x-coordinate represents a value on thestart color #11accd, start text, space, h, o, r, i, z, o, n, t, a, l, end text, end color #11accd axis.

The y-coordinate represents a value on the start color #1fab54, start text, v, e, r, t, i, c, a, l, end text, end color #1fab54 axis.

The y-coordinate represents a value on the start color #1fab54, start text, v, e, r, t, i, c, a, l, end text, end color #1fab54 axis.

**Example:**

Plot the point left parenthesis, 6, comma, 4, right parenthesis.

For left parenthesis, start color #11accd, 6, end color #11accd, comma, start color #1fab54, 4, end color #1fab54, right parenthesis our x-coordinate is start color #11accd, 6, end color #11accd, and our y-coordinate is start color #1fab54, 4, end color #1fab54.

Let's start by going right to start color #11accd, 6, end color #11accd on the x-axis:

Now we go up to start color #1fab54, 4, end color #1fab54 on the y-axis, and plot the point left parenthesis, start color #11accd, 6, end color #11accd, comma, start color #1fab54, 4, end color #1fab54, right parenthesis:

## Identifying points

To determine the coordinates (or ordered pair) of a given point, we need to count the start color #11accd, start text, h, o, r, i, z, o, n, t, a, l, end text, end color #11accd and start color #1fab54, start text, v, e, r, t, i, c, a, l, end text, end color #1fab54 distance of the point from the start color #e84d39, start text, o, r, i, g, i, n, space, left parenthesis, 0, comma, space, 0, right parenthesis, end text, end color #e84d39.

**Example:**

Use the following coordinate plane to determine the ordered pair for the given point.

Let's start by counting the distance from left parenthesis, 0, comma, 0, right parenthesis to the given point on the x-axis:

The point is start color #11accd, 3, end color #11accd units to the right of the origin.

Now let's count the distance from left parenthesis, 0, comma, 0, right parenthesis to the given point on the y-axis:

The point is start color #1fab54, 1, end color #1fab54 unit above the origin.

The coordinates of the point are left parenthesis, start color #11accd, 3, end color #11accd, comma, start color #1fab54, 1, end color #1fab54, right parenthesis.

- Graph points are easy and fun to do.(146 votes)
- Once you understand them they aren't hard(54 votes)

- why does the zero go second?

for example: (2,0)

why not (0,2) ?(9 votes)- because it is 2 down, 0 up.(52 votes)

- Coordinate grids are so easy.(48 votes)
- They call this a challenge. well... it wasn't(28 votes)
- Your right, my dudes(12 votes)

- why do we do the x axis before the y axis(15 votes)
- x comes before y in the alphabet, but I honestly don't know.(23 votes)

- how does this work im confused?(17 votes)
- so what you do is you find the number on the x line and put that number down then you find the number on the y line and put that number down(23 votes)

- I don't get this(11 votes)
- ill tell you how to remember if y axis or x axis comes first in the alphabets first x comes then y so first x always :>(17 votes)

- It says it doesn't understand my answer(24 votes)
- Did you put a letter?(7 votes)

- I got practice set 2 right but it said I got it wrong? PLEASE FIX!(19 votes)
- read the instrucions carfully(1 vote)

- How come it’s Y and X why can’t it be another letter like D!(10 votes)
- I believe its because Y and X are almost the last letters in the alphabet, so it will be eaisier or harder for you to know wich one comes first. For exampl if the two letters were "D" and "E", you would know "D" comes first, but because the two letters and X and Y it's harder because they are almost the last in the alphabet, unless you know you alphabet real well, so they wanted to throw in a small challenge i guess.(13 votes)
