Question

The graph shows the linear relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant has been growing. Which statements are correct? Check all that apply. The rate of change is 4. The rate of change is 1. The rate of change is . The plant grows 4 cm in 1 week. The plant grows 1 cm in 4 weeks

Answer 1

Answer:

A. The rate of change is 4,  C. The rate of change is 4/1,  and D. The plant grows 4 cm in 1 week.

Step-by-step explanation:

It was right on edge

Answer 2

I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).

Slope = (20 - 10)/(50 - 30) = 1/2

The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.
