When Charlotte planted her tomato plant, it grew 3 inches in one week. After 5 weeks, the tomato plant was 23 inches tall. Assume the relationship is linear. Find and interpret the rate of change and the initial value.

• Rate of Change = 3, Initial Value = 8

• Rate of Change = 8, Initial Value = 3

• Rate of Change = 5, Initial Value = 8

• Rate of Change = 3, Initial Value = 23
