Hello! Remember you have to write complete questions in order to get exact and good answers. However, I found a similar question on the internet which is attached below and want to explain it to you. Here we know that the graph is a line that passes through the points [tex](30,10) \ and \ (50,20)[/tex] So the slope is:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ \\ (x_{1},y_{1})=(30,10) \\ \\ (x_{2},y_{2})=(50,20) \\ \\ \\ m=\frac{20-10}{50-30}=\frac{1}{2}[/tex]
From the slope we know that the plant grows 1 cm every two days.
