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)
The graph that represents the relationship between Tony's age and Maria's age is a straight line that slopes upward, indicating that as Tony's age (x) increases, Maria's age (y) also increases.
I'm sorry, but I cannot see or interpret images. However, I can explain how to determine the relationship between Tony's age (x) and Maria's age (y) based on the given information.
Since Tony is four years younger than Maria, we can express this as an equation:
x = y - 4
This equation represents a linear relationship between x and y.
In terms of a graph, the relationship can be represented by a straight line with a slope of 1 and a y-intercept of -4.
So, the correct graph would be the one that represents a straight line with a slope of 1 passing through the point (0,-4).
To determine the relationship between Tony's age and Maria's age, we are given that Tony is four years younger than Maria. Let's represent Tony's age as x and Maria's age as y.
Since Tony is four years younger than Maria, we can express this relationship as:
x = y - 4
To graph this relationship, we can draw a scatter plot, with Tony's age (x) on the x-axis and Maria's age (y) on the y-axis.
Since x is equal to y minus 4, we can generate a set of points to plot on the graph. For example, if Maria's age is 10, Tony's age would be 10 - 4 = 6.
By plotting several points using different values for y, we can establish the relationship between Tony's age and Maria's age on the graph.
Based on the given information, we can conclude that the graph representing the relationship between Tony's age (x) and Maria's age (y) will be a straight line with a negative slope. The line will slope upwards from left to right because as Maria's age increases, Tony's age also increases but at a slower rate due to the four-year age difference.
