The slope of the equation represents the rate of change of the dependent variable (height in feet) with respect to the independent variable (time in weeks). In this case, the slope is 3/2. Therefore, the correct interpretation of the slope is:
The sunflower's height increases by an additional 3/2 foot each week.
A botanist collected data on the growth of sunflowers to maturity. She modeled the equation ◂=▸y=x+ 3 2 for the line of best fit. The independent variable, x, is time in weeks and the dependent variable, y, is height in feet. What does the slope mean in this context? (1 point) Responses The sunflower's height increases by an additional 3/2 foot each week. The sunflower's height increases by an additional 3/2 foot each week. The sunflower's height increases by an additional 1 foot each week. The sunflower's height increases by an additional 1 foot each week. The sunflower's starting height is 3/2 foot. The sunflower's starting height is 3/2 foot. The sunflower's age increases by an additional 3/2 week every 1 foot. The sunflower's age increases by an additional 3/2 week every 1 foot. The sunflower's starting height is 1 foot. The sunflower's starting height is 1 foot.
