Solution

Substitute numbers in for known x values.
x y = x - 6 y
11   11 - 6   5
9   9 - 6   3
14   14 - 6   8

To find the unknown x value, take the known y value and add 6.

Fill in the missing values and find the rule that applies to the table. Write the rule in the format "y = ... ".

#Correct AnswerYour Answer
1Pearl has 8 more notebooks than Miguel.
Rule:
# notebooks Miguel has (x)# notebooks Pearl has (y)
2
6
8
10
Solution
"Pearl has 8 more notebooks than Miguel." means
Number of notebooks Pearl has is 8 more than the number of notebooks Miguel has
y = + 8 x

So you get, y = x + 8
#Correct AnswerYour Answer
2Maria has 6 fewer CDs than Mary.
Rule:
# CDs Mary has (x)# CDs Maria has (y)
14
11
12
13
Solution
"Maria has 6 fewer CDs than Mary." means
Number of CDs Maria has is 6 fewer than the number of CDs Mary has
y = - 6 x

So you get, y = x - 6

Fill in the missing values and find the rule that applies to the table. Write the rule in the format "y = ... ".

#Correct AnswerYour Answer
1Heptagons have 7 sides.
Rule:
Number of heptagons (x)Number of sides (y)
1
4
9
3
Solution
"Heptagons have 7 sides." means that there are 7 sides per heptagon.
For the number of sides, multiply by the rate (sides per heptagon).
number of sides = sides per heptagon × number of heptagons
y = 7 × x

So you get, y = 7x
#Correct AnswerYour Answer
2Stools have 3 legs.
Rule:
Number of stools (x)Number of legs (y)
8
1
7
5
Solution
"Stools have 3 legs." means that there are 3 legs per stool.
For the number of legs, multiply by the rate (legs per stool).
number of legs = legs per stool × number of stools
y = 3 × x

So you get, y = 3x
