Question

2. When Sarah planted her tomato plant, it grew 3 inches in

one week. After 5 weeks, the plant was 23 inches tall.
Assume the relationship is linear. Find and interpret the rate
of change and the initial value.

Answer 1

Explanation:

the plant grows 3 inches in 1 week......so in 5 weeks, it will have grown

(5 * 3) = 15 inches...but it was 23 inches.....therefore, the initial value of the plant was (23 - 15) = 8 inches

another words, when she planted the plant, it was already 8 inches tall....it then grew 3 inches per week.

ur equation would be : y = 3x + 8.......with 3 being the slope(or rate of change) and 8 being the initial value (or the y intercept)
