For a science project, Miranda will monitor the growth of two different plants, Plant 1 and Plant 2. At the start of the project plant 1 is 18 cm tall and plant 2 is 4cm tall. plant 1 is expected to grow at a rate of 3 cm a week and plant 2 is expected to grow at a rate of 5cm Part A: What is the solution to the system of equations in Miranda's graph?

Part B: What is the meaning of the solution to the system of equations in the context of Miranda's plant growth?
