Answer
Answer:
Megan's plant grew at a faster rate. The rate of Megan's plant is 2.5 inches per week and the rate of Suzanne's plant is 2 inches per week.
Explanation:
Step1: Calculate rate for Megan's plant
The rate of change (slope) formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Using the points $(1,4.5)$ and $(2,7)$ from Megan's plant data. $m_{Megan}=\frac{7 - 4.5}{2 - 1}=\frac{2.5}{1}=2.5$ inches per week.
Step2: Calculate rate for Suzanne's plant
Using the points $(1,5)$ and $(2,7)$ from Suzanne's plant graph. $m_{Suzanne}=\frac{7 - 5}{2 - 1}=\frac{2}{1}=2$ inches per week.
Step3: Compare the rates
Since $2.5>2$, Megan's plant grew at a faster rate.
