1. 1.3 Linear Graphs

2. Graphing Lines from a
Table
• Corresponding x and y values from the
table make ordered pairs.
• Plot them on the graph.
▫ x moves left/right
▫ y moves up/down
• Connect with a straight line.
• Don’t forget arrows at the ends!

3. Example 1
• Graph: x -1 0 1 2
y 6 4 2 0

4. You Try!
• Graph:
x y
-6 6
-3 5
0 4
3 3
6 2

5. Writing a Table from a Graph
• Find points on the line that cross
exactly on the grid.
YES! NO!
•Write them as ordered pairs.
•Working from left to right, transfer x and
y values to a table.

6. Example 2
• Fill in the table for the graph shown.
x y

7. You Try!
• Fill in the table for the graph shown.
x y

8. Sequences, Tables, and Graphs
• Given any format, you can find the other
two!
• From sequence:
make table first, then graph
• From table:
use it to write sequence and graph
• From graph:
make table first, then sequence

9. Example 3
• Sequence: 1, 3, 5, 7, …
x
y

10. Example 4
• Sequence:
x 0 2 4 6
y -5 -3 -1 1

11. Example 5
• Sequence:
x
y
