To determine if the relationship between two variables is linear or nonlinear, we need to analyze the pattern of the data in the table.
Based on the given table:
x: 1, 2, 3, 4
y: 5, -1, -7, -13
Let's calculate the differences between successive values of x and y:
Δx: 1, 1, 1
Δy: -6, -6, -6
If the values of Δy are constant, it indicates a linear relationship. In this case, Δy is -6 for each Δx. Therefore, the relationship between the variables x and y is linear.
Additionally, we can identify whether the relationship is increasing or decreasing based on the values of y. In this case, as x increases, y decreases. Therefore, the relationship is decreasing.
In conclusion, the relationship between the variables x and y in the given table is linear and decreasing.
