A botanist collected data on the growth of sunflowers to maturity. She modeled the equation y = x + 1/2 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?
Responses

The sunflower's starting height is 1/2 foot
The sunflower's starting height is 1 half foot each week.
The sunflower's starting height is 1 foot.
