A botanist collected data on the growth of sunflowers to maturity. She modeled the equation y = x + 12
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?
1 answer
In this context, the y-intercept represents the initial height of the sunflowers when they were planted. It indicates that when the time, x, is zero (at the beginning), the height of the sunflowers, y, is 12 feet.
