Answer:
x y
15 -1
12 0
9 1
6 2
3 3
0 4
Explanation:
This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.
![m = (y_2-y_1)/(x_2-x_1)=(4-0)/(0-12) =(4)/(-12) =- (1)/(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ug5giceqxpdx1313numgb6360i0vz6rcgh.png)
This means for every 3 units made in the input, the function moves down 1 output.
x y
15 -1
12 0
9 1
6 2
3 3
0 4
