Answer:
The answer is the graph on the right hand side
Explanation:
Order pairs (x,y) are given by Series S and T where
S: starts with 10 and goes by the rule of subtract 1
T: starts with 10 and goes by the rule of subtract 2
The points represented by the pairs are (10,10) at the start;
second point = (10-1, 10-2) = (9,8)
third point = (9-1, 8-2) = (8,6)
and so on.
So the answer is the graph on the right hand side.
