1. Objective & Essential Understanding
OBJECTIVE: Students will be able to graph linear equations by drawing up coordinate tables.
ESSENTIAL UNDERSTANDING: Choose X. Solve for Y. Then you have a coordinate pair. Graph it!

2. What is a linear equation?
Silently think about the answer & jot down your ideas
What is a linear equation?
A linear equation creates a line. Two examples: Y = X and Y = X + 2

3. How do we graph a linear equation?
Silently think about the answer & jot down your ideas
How do we graph a linear equation?
Create a Coordinate Table
Y = X + 2
X X+ 2 Y

4. Number One: Y = X + 2
Y = X + 2 X
X + 2 = Y
Coordinate Pair 1 2 3 4

5. Number Two: Y = X + 1
Y = X + 1 X
X + 1 = Y
Coordinate Pair 1 2 3 4

6. Number Three: Y = X
Y = X X
X = Y
Coordinate Pair 1 2 3 4

7. Number Four: Y = X + 3
Y = X + 3 X
X + 3 = Y
Coordinate Pair -2 -1 1 2

8. Number Five: Y = X - 1
Y = X - 1 X
X -1 = Y
Coordinate Pair -2 -1 1 2

9. Number Six: Y = X - 3
Y = X - 3 X
X - 3 = Y
Coordinate Pair -2 -1 1 2

10. Number Seven: Y = 2X
Y = 2X X
2X = Y
Coordinate Pair -2 -1 1 2

11. Number Eight: Y = 3X
Y = 3X X
3X = Y
Coordinate Pair -2 -1 1 2

12. Number Nine: Y = 2X + 1 Y = 2X + 1 X 2X + 1 = Y Coordinate Pair -2 -1-1 1 2

13. Number Ten: Y = 2X + 3 Y = 2X + 3 X 2X + 3= Y Coordinate Pair -2 -1 1-1 1 2

14. Number Eleven: Y = 2X - 1 Y = 2X - 1 X 2X -1 = Y Coordinate Pair -2 -1-1 1 2

15. Number Twelve: Y = 2X - 2 Y = 2X - 2 X 2X -2 = Y Coordinate Pair -2 -1-1 1 2
