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

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

1. y = (-2/3)x + 2/3

Initial value = 2/3
Rate of change = -2/3

2. y = (2/3)x - 2/3
Initial value = -2/3
Rate of change = 2/3

3. y = (2/3)x - 2
Initial value = -2
Rate of change = 2/3

4. y = (3/2)x + 1/6
Initial value = 1/6
Rate of change = 3/2
