Question

Which statements are correct? Check all that apply. The graph shows the linear relationship between the height of a plant (in centimeters) and the ume (in weeks) that the plant has been growing. The rate of change is 4. The rate of change is 1. 24 O The rate of change is 20 1 16 12 The plant grows 4 cm in 1 week. 0The plant grows 1 cm in 4 weeks. 8 4 Time (weeks)

Answer 1

as shown in the graph, there is a relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant has been growing.

so, the unit rate is = height over the time

so, the unit rate represents the slope of the line

So, unit rate =

`(12-8)/(1-0)=(4)/(1)=4\text{ cm/week}`

so, the correct statements are:

The rate of change is 4

The rate of change is (4/1)

The planet grows 4 cm in 1 week
