Question

Which is a graph of the ordered pairs formed from the corresponding terms of Pattern S and Pattern T? Pattern S starts at 10 and uses the rule "Subtract 1". Pattern T starts at 10 and uses the rule "Subtract 2". 10 10 20 8 6 6 4 2 2 2 0 0 0- 0 1 2 3 1 5 6 7 8 9 10 0 1 2 3 4 5 6 7 8 9 10 0 1 2 3 5 6 7 8 9 10

Answer 1

We have that for pattern S, the pattern starts at 10 and substracts 1, then we have:

`S\colon10,9,8,7,6,5,4,3,2,1`

then, for pattern T, it starts at 10 and then substracts 2, then:

`T\colon10,8,6,4,2,0`

if we write these patterns as ordered pairs, starting from left to right, with the form (s,t), we have:

`(10,10),(9,8),(8,6),(7,4),(6,2)_{}`

notice that only graph 2 represents these ordered pairs, therefore, the correct option is the middle graph
