Remember: Make a list from each rule. Line up the lists, then plot each pair: across first, then up.
Make the lists and pair them
1
Rule A adds 2. Rule B adds 8. Both start at 0. What is the 4th term of Rule A?
2
What is the 4th term of Rule B?
3
The 4th terms make a pair. Which pair?
(32, 8)(8, 32)(2, 8)
4
Rule A adds 1 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 5. Rule B adds 10. Which place is the pair 20 and 40?
6
Rule A adds 3. Rule B adds 9. The 3rd terms make the pair 9 and 27.
TrueFalse
How the lists compare
7
Rule A adds 6. Rule B adds 2. Each B term is 3 times as big as the A term in the same place.
TrueFalse
8
Rule A adds 4. Rule B adds 12. Each B term is times as big as the A term in the same place.
9
Join the two rules to how the lists compare.
1A adds 2, B adds 10
2A adds 5, B adds 10
3A adds 3, B adds 9
4A adds 4, B adds 24
AB is 6 times A
BB is 2 times A
CB is 3 times A
DB is 5 times A
10
Rule A adds 3. Rule B adds 6. Number the pairs from the 1st place (1) to the 4th place (4).
(9, 18)
(3, 6)
(12, 24)
(6, 12)
11
Rule A adds 1 and Rule B adds 5. Across is A and up is B. The dot P shows a pair. Which pair is P?
(2, 10)(10, 2)(2, 5)
12
Rule A adds 6. Rule B adds 18. The 5th term of Rule A is 30. What is the 5th term of Rule B?
13
Rule A adds 2 and Rule B adds 10. Write how you know every B term is 5 times the A term.
