Determine the initial value and the rate of change of the linear function.

1. The initial value is 0, and the rate of change is 12.
2. The initial value is 2, and the rate of change is 2.
3. The initial value is 0, and the rate of change is 2.
4. The initial value is −6, and the rate of change is 2.

1. Function: y = 12x + 0 (or y = 12x) Initial value: 0, Rate of change: 12

2. Function: y = 2x + 2 Initial value: 2, Rate of change: 2
3. Function: y = 2x + 0 Initial value: 0, Rate of change: 2
4. Function: y = 2x - 6 Initial value: -6, Rate of change: 2
