# 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.
A coordinate grid is labeled 0 through 9 on the x-axis and the y-axis. A blue arrow moves right along the x-axis. A green arrow moves up along the y-axis.
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.
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:
A coordinate grid. The x-axis is labeled 1 to 9. The y-axis is labeled 1 to 9. A blue arrow moves right along the x-axis from the origin to the 6.
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:
A coordinate grid. The x-axis is labeled 1 to 9. The y-axis is labeled 1 to 9. A blue arrow moves right along the x-axis from the origin to the 6. A green arrow moves up 4 units from the 6 on the x-axis to align with 4 on the y-axis. A point labeled (6,4) is plotted at the end of the green arrow.

## Practice set 1: Graphing points

Problem 1A

## 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.
A coordinate grid is labeled 0 through 6 on the x-axis and the y-axis. A blue arrow moves right along the x-axis. A green arrow moves up along the y-axis. There is a red point at the origin. A point is plotted 3 units to the right and 1 unit up from the origin.
Example:
Use the following coordinate plane to determine the ordered pair for the given point.
A coordinate grid is labeled 0 through 6 on the x-axis and the y-axis. A point is plotted 3 units to the right and 1 unit up from the origin.
Let's start by counting the distance from left parenthesis, 0, comma, 0, right parenthesis to the given point on the x-axis:
A coordinate grid is labeled 0 through 6 on the x-axis and the y-axis. A point is plotted 3 units to the right and 1 unit up from the origin. A blue arrow moves right along the x-axis from the origin to the 3.
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:
A coordinate grid is labeled 0 through 6 on the x-axis and the y-axis. A point is plotted 3 units to the right and 1 unit up from the origin. A green arrow moves up 1 unit from the 3 on the x-axis to align with the 1 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.

## Practice set 2: Identifying points

Problem 2A
What is the x-coordinate of the point plotted below?
A coordinate grid is labeled 0 through 6 on the x-axis and the y-axis. A point is plotted 4 units to the right and 3 units up from the origin.

• Coordinate grids are so easy.
• I know right!?
• why does the zero go second?
for example: (2,0)
why not (0,2) ?
• Because the 0 is the X, so it goes at the start, if the 0 was the Y then it can go second, but its not
• They call this a challenge. well... it wasn't
• how does this work im confused?
• 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
• I got practice set 2 right but it said I got it wrong? PLEASE FIX!
• How come it’s Y and X why can’t it be another letter like D!
• 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.
• It says it doesn't understand my answer
