The rate of change, or the slope, is 1.
The rate of change, or the slope, can be found by examining the change in the plant's height (y) with respect to the number of days (x). Let's calculate the slope using the given data:
We can choose two points from the table, for example, (7, 4) and (14, 11). Then we can use the formula for the slope:

Substituting the values, we get:


m=1
So, the rate of change, or the slope, is 1.
