Final answer:
The slope of the graph represents the growth rate of the seedling in inches per week.
Step-by-step explanation:
The slope of the graph of the equation ℎ= 3/4 w+9/4 represents the rate at which the height of the seedling increases each week. In this case, the slope is 3/4, which means that for every increase of 1 week, the height of the seedling increases by 3/4 inches.
So, the slope of the graph represents the growth rate of the seedling.
