Remember: Make a list from each rule, line up the terms, and plot each pair: across first, then up.
Make the lists and pair them
1
Rule A adds 4. Rule B adds 12. Both start at 0. What is the 6th term of Rule A?
2
The 6th terms of those rules make a pair. Which pair?
(24, 72)(72, 24)(24, 36)
3
Rule A adds 9. Rule B adds 27. Which place is the pair 36 and 108?
4
Rule A adds 2 and Rule B adds 3. Across is A and up is B. Which graph plots the first three pairs?
Graph 1Graph 2Graph 3
5
Rule A adds 8. Rule B adds 40. Each B term is times as big as the A term in the same place.
6
Rule A adds 5 and Rule B adds 15. The 7th terms make the pair 35 and 105.
TrueFalse
Think about the rules
7
Rule B adds 3 times as much as Rule A, so each B term is 3 more than the A term in the same place.
TrueFalse
8
Look at the lists. Rule B adds each time.
9
Join each pair of rules to the 5th pair they make.
1A adds 2, B adds 6
2A adds 3, B adds 12
3A adds 4, B adds 8
4A adds 5, B adds 25
A(20, 40)
B(10, 30)
C(15, 60)
D(25, 125)
10
Number the steps to find how many times as big Rule B is as Rule A.
Line up the terms in the same place
Divide a B term by the A term in its place
Say: each B term is that many times the A term
Make a list for each rule
11
Rule A adds 3 and Rule B adds 6. Which pair is NOT made by these rules?
(15, 35)(9, 18)(12, 24)
12
Rule A adds 1 and Rule B adds 3. Across is A and up is B. Which dot is NOT a pair of these rules?
PQRS
13
Rule A adds 4 and Rule B adds 20. Write how you know every B term is 5 times the A term, and give the 5th pair.
