Great! So, how to I plot a point and name it?!
Let’s try some coordinate grid EXAMPLES.
Reasoning Mind Academy: Coordinate Grid
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!
Reasoning Mind Academy: Coordinate Grid
Example 1) Graph point R at (4, 5) on the grid provided below.
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!
Reasoning Mind Academy: Coordinate Grid
Example 1) Graph point R at (4, 5) on the grid provided below.
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! )
Reasoning Mind Academy: Coordinate Grid
Example 1) Graph point R at (4, 5) on the grid provided below.
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.
