Need help with this ​
snow_tiger [21]

Answer:

x       y

15     -1

12     0

9       1

6       2

3       3

0       4

Step-by-step 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 = \frac{y_2-y_1}{x_2-x_1}=\frac{4-0}{0-12} =\frac{4}{-12} =- \frac{1}{3}

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
