The graph shows the linear relationship between the height of a plant (in centimeters) and the time (in weeks) that the plant ha
s 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

I located a graph that matches this problem, so I assume this is the one to reference. To find the rate of change, calculate the slope between two points on the line, such as (30,10) and (50,20).
Slope = (20 - 10) / (50 - 30) = 10/20 = 1/2
Thus, the rate of change is 0.5 cm per week, or equivalently, 1 cm every 2 weeks.
Slope = (20 - 10) / (50 - 30) = 10/20 = 1/2
Thus, the rate of change is 0.5 cm per week, or equivalently, 1 cm every 2 weeks.

Density can be defined as:
Where:
m is mass
V stands for volume
To isolate the mass, we derive:
Volume can be expressed as:
We then use the following conversion:
After applying the conversion, we arrive at:
Additionally, we have these conversions:
When we apply these conversions for density, we conclude:
Finally, the mass of the water required is:
