Answer:
table 1
Explanation:
You want to know which of the four given tables represents a linear function.
1.
The x-values increase by 2; y-values decrease by 2/3. The rate of change is constant. This is a linear function.
2.
The x-values increase by 2; y-values decrease, then increase again. The rate of change is not constant. This is not a linear function.
3.
The x-values increase by 2; y-values increase by changing amounts. The rate of change is not constant. This is not a linear function.
4.
The x-values repeat. This is not a function.
