7
Solution

Substitute numbers in for known x values.
x y = x + 2 y
5   y = x + 2   =   5 + 2   =   7   7
4   y = x + 2   =   4 + 2   =   6   6
7   y = x + 2   =   7 + 2   =   9   9

To find the unknown x value, take the known y value and subtract 2.

8
Solution

Substitute numbers in for known x values.
x y = x + 3 y
7   y = x + 3   =   7 + 3   =   10   10
6   y = x + 3   =   6 + 3   =   9   9
8   y = x + 3   =   8 + 3   =   11   11

To find the unknown x value, take the known y value and subtract 3.

36
Solution

Substitute numbers in for known x values.
x y = x × 4 y
7   y = x × 4   =   7 × 4   =   28   28
8   y = x × 4   =   8 × 4   =   32   32
4   y = x × 4   =   4 × 4   =   16   16

To find the unknown x value, take the known y value and divide by 4.

20
14
10
Solution

Substitute numbers in for known x values.
x y = x ÷ 2 y
20   y = x ÷ 2   =   20 ÷ 2   =   10   10
14   y = x ÷ 2   =   14 ÷ 2   =   7   7
10   y = x ÷ 2   =   10 ÷ 2   =   5   5

To find the unknown x value, take the known y value and multiply by 2.

Complexity=1, Mode=word

Fill in the missing values and find the rule that applies to the table. Write the rule in the format "y = ".
#Correct AnswerYour Answer
1Miguel has 7 fewer pens than Mary.
Rule:
# pens Mary has (x)# pens Miguel has (y)
9
10
16
17
Solution
"Miguel has 7 fewer pens than Mary." means
Number of pens Miguel has is 7 fewer than the number of pens Mary has
y = - 7 x

So you get, y = x - 7
#Correct AnswerYour Answer
2Paul has 2 fewer notebooks than Sharon.
Rule:
# notebooks Sharon has (x)# notebooks Paul has (y)
7
5
6
10
Solution
"Paul has 2 fewer notebooks than Sharon." means
Number of notebooks Paul has is 2 fewer than the number of notebooks Sharon has
y = - 2 x

So you get, y = x - 2

1Sharon runs 5 miles per hour.
Rule:
Number of hours (x)Number of miles (y)
4
8
3
9
Solution
For the number of miles, multiply by the rate (miles per hour).
number of miles = miles per hour × number of hours
y = 5 × x

So you get, y = 5x
#Correct AnswerYour Answer
2Each box contains 7 CDs.
Rule:
Number of boxes (x)Number of CDs (y)
4
9
6
1
Solution
"Each box contains 7 CDs." means that there are 7 CDs per box.
For the number of cds, multiply by the rate (CDs per box).
number of cds = CDs per box × number of boxes
y = 7 × x

So you get, y = 7x

Complexity=3, Mode=givenRule

Use the given rule to fill in the missing values.
#Correct AnswerYour Answer
1
y = 9x + 10
Input (x)Output (y)
3
7
8
1
Solution

Substitute numbers in for known x values.
x y = 9x + 10 y
3   y = 9x + 10   =   9(3) + 10   =   37   37
7   y = 9x + 10   =   9(7) + 10   =   73   73
8   y = 9x + 10   =   9(8) + 10   =   82   82
1   y = 9x + 10   =   9(1) + 10   =   19   19

7
Solution

Substitute numbers in for known x values.
x y = 4x - 1 y
2   y = 4x - 1   =   4(2) - 1   =   7   7
8   y = 4x - 1   =   4(8) - 1   =   31   31
10   y = 4x - 1   =   4(10) - 1   =   39   39
7   y = 4x - 1   =   4(7) - 1   =   27   27
