Graph 2 is the correct option

Step-by-step explanation:

We are given that,

In the graph of ordered pairs formed for Pattern S and Pattern T, the condition for the graph is,

Pattern S starts at 10 and uses the rule 'Subtract 1'.

Pattern T starts at 10 and uses the rule 'Subtract 2'.

This means that in the corresponding graph, the maximum point is 10 on the T-axis.

Also, the points on S-axis are obtained by the subtracting 1 from the previous number. That is, the co-ordinates on S-axis vary by 1 unit.

Moreover, the points on T-axis are obtained by the subtracting 2 from the previous number. That is, the co-ordinates on T-axis vary by 2 units.

Hence, the second graph satisfies the given condition.
