Tony and his sister Maria have the same birthday, but Tony is four years YOUNGER than Maria. Let the variable x represent Tony’s age and y represent Maria’s age. Which graph represents the relationship between Tony’s age and Maria’s age? (Circle your answer)

Answer 1

The correct graph representing the relationship between Tony's age and Maria's age would be:

x-axis: Maria's age (y)
y-axis: Tony's age (x)

The graph should show a straight line with a positive slope, indicating that as Maria's age increases, Tony's age also increases.
