1. GRAPHING LINEAR EQUATIONS

2. What is the value of 2x + 1 if
2(-2) + 1 -3 -1
x = -1?
2(-1) + 1 1
2(0) + 1
x = 0? 3
2(1) + 1
x = 1?

3. We will call this columnx
2x + 1 -2
2(-2) + 1 -3 -1
2(-1) + 1
2(0) + 1 1
2(1) + 1 3 y
This is the linear equation y = 2x + 1

4. Linear means “line” By graphing these values, we can see a visual representation of the line y = 2x + 1

5. x y -2 -3 -1 1 3

6. y = 2x + 1

7. TRY y = -3x + 1

8. y = -3x + 1 x
-3x + 1 y -1 1
-3(-1) + 1 4
-3(0) + 1 1
-3(1) + 1 -2
You can choose any values for x
(at least 3)

9. x y -1 4 1 -2

11. TRY y = 5 +2x

12. y = 5 + 2x x
5 + 2x y -2 -1
5 + 2(-2) 1
5 + 2(-1) 3
5 + 2(0) 5
You can choose any values for x
(at least 3)

13. x y -2 1 -1 3 5

15. TRY y = -4x + 2

16. y = -4x + 2 x
-4x + 2 y -1 1
-4(-1) + 2 6
-4(0) + 2 2
-4(1) + 2 -2
You can choose any values for x
(at least 3)

17. x y -1 6 2 1 -2
