Question

A botanist collected data on the growth of sunflowers to maturity. She modeled the equation y = x +

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 y-intercept mean in this context?
Responses

Answer 1

In this context, the y-intercept represents the initial height of the sunflowers when they were first measured (at x=0 weeks). It indicates the starting point of the growth process before any additional growth occurred.
