2. I Do:
y = 2x + 2
Step 1: Complete the function table for the given equation.
Input x 1 2 3 4
Output y 6 8 10 4
y = 2x + 2
y = 2x + 2
y = 2x + 2
y = 2x + 2
y = 2(4) + 2
y = 2(2) + 2
y = 2(3) + 2
y = 2(1) + 2
y = 4 + 2
y = 6 + 2
y = 8+ 2
y = 2 + 2
y = 8
y = 10
y = 6
y = 4

3. Step 2: Use the table to write the ordered pairs.
y = 2x + 2
Input x 1 2 3 4
Output y 4 6 8 10
(___ , ____) (___ , ____) (___ , ____) (___ , ____) x y x y x y x y 1 4 2 6 3 8 4 10

4. 1 4 2 6 3 8 4 10 Step 3: Graph the ordered pairs and label each point.
(___ , ____) (___ , ____) (___ , ____) (___ , ____) 1 4 2 6 3 8 4 10
Run before you jump
(4 , 10)
(3 , 8)
(2 , 6)
x before y
(1 , 4)

5. y = x - 5 5 6 7 8 1 2 3 y = x - 5 y = x - 5 y = x - 5 y = x - 5
I Do:
y = x - 5
Step 1: Complete the function table for the given equation.
Input x 5 6 7 8
Output y 1 2 3
y = x - 5
y = x - 5
y = x - 5
y = x - 5
y = 8 - 5
y = 5 - 5
y = 6 - 5
y = 7 - 5
y = 3
y = 0
y = 1
y = 2

6. Step 2: Use the table to write the ordered pairs.
y = x - 5
Input x 5 6 7 8
Output y 1 2 3
(___ , ____) (___ , ____) (___ , ____) (___ , ____) x y x y x y x y 5 6 1 7 2 8 3

7. 5 6 1 7 2 8 3 Step 3: Graph the ordered pairs and label each point.
(___ , ____) (___ , ____) (___ , ____) (___ , ____) 5 6 1 7 2 8 3
Run before you jump
x before y

13. How can I write the rule using symbols and numbers instead of words?
I Do:
Step 1: Write an equation for rule. Then complete the function table.
Rule: Multiply by 3
Equation:
y= 3x
How can I write the rule using symbols and numbers instead of words?
I know that “multiply” can be replaced with a an “x” or a “●” or the number can be right next to the variable and that means multiply.
Input x 3 4 5 6
Output y 9 12 15 18
y= 3x
y= 3(3)
y= 3 ● 3
y= 9
y= 3x
y= 3(4)
y= 3 ● 4
y= 12
y= 3x
y= 3(5)
y= 3 ● 5
y= 15
y= 3x
y= 3(6)
y= 3 ● 6
y= 18

14. Step 2: Use the table to write the ordered pairs.
y = 3x
Input x 3 4 5 6
Output y 9 12 15 18
(___ , ____) (___ , ____) (___ , ____) (___ , ____) x y x y x y x y 3 9 4 12 5 15 6 18

15. Step 3: Graph the ordered pairs and label each point.
(___ , ____) (___ , ____) (___ , ____) (___ , ____) 3 9 4 12 5 15 6 18
