REMEMBER: A coordinate grid is made up of two perpendicular number lines. It has a __ axis called the . It also has a axis called the .




REMEMBER: A coordinate grid is made up of two perpendicular number lines. It has a horizontal axis called the x-axis . It also has a vertical axis called the y-axis .




Definition: The x-axis and y-axis intersect at a point called the . ( , )

REMEMBER: We name a point using an ordered pair of numbers. These coordinates describe the location of a point.



y-coordinate


Definition: The first number in the ordered pair is called the ; it names the distance either or from the origin along the x-axis.



y-coordinate


Definition: The first number in the ordered pair is called the x-coordinate ; it names the distance either

right or left from the origin along the x-axis.



y-coordinate


Definition: The second number in the ordered pair is called the ; it names the distance either or from the origin along the y-axis.



y-coordinate


Definition: The second number in the ordered pair is called the y-coordinate ; it names the distance either up or down from the origin along the y-axis.

Great! So, how to I plot a point and name it?!

Let’s try some coordinate grid EXAMPLES.


Example 1) Graph point R at (4, 5) on the grid provided below.

Step 1: Draw and number the and on grid

paper.

Step 2: Identify the and .

Step 3: ALWAYS BEFORE YOU UP OR DOWN!



Step 1: Draw and number the x-axis and y-axis on grid paper.

Step 2: Identify the x-coordinate and y-coordinate .

Step 3: ALWAYS RUN BEFORE YOU JUMP UP OR DIVE DOWN!



First, move to the right or left from the origin using the to locate the x-coordinate. Then, move up or down from the x-axis using the

to locate the y-coordinate.

Step 4: Mark a and it with its coordinates or a

letter! (If you have a FIRST & LAST name, make sure the point does too! )



First, move to the right or left from the origin using the x-axis to locate the x-coordinate. Then, move up or down from the x-axis using the

y-axis to locate the y-coordinate.

Step 4: Mark a point and name/label it with its coordinates or a letter! (If you have a FIRST & LAST name, make sure the point does too! )


Example 2)

If given a data table, we can also graph points to create a line graph! Use the steps we learned in example one to plot your points on a line graph.

x Day 1 3 5 7 9

y Height (cm)

4 8 10 11 14


Example 3)

The line graph below shows temperature changes in Galveston for one day.


Example 4) Which of the points: x, y, or z has the ordered pair (4, 3)?


Example 4) Which of the points: x, y, or z has the ordered pair (4, 3)?

z


Example 5) Label each axis with the letter x or y the standard way.

Plot the following points on the grid above:

a. (2,2)b. (0,3)c. (3,1)
