The slope of the regression line is 15, which means that for every additional sunflower per acre, the number of honeybees per acre is expected to increase by 15.
The y-intercept of the regression line is 11, which means that if there are no sunflowers in the neighborhood (x=0), there are still 11 honeybees per acre present. This represents the baseline number of honeybees in the neighborhood independent of the number of sunflowers.
A scientist studied the relationship between the number of sunflowers, x, per acre and the number of honeybees, y, per acre in a neighborhood. She modeled the relationship with a scatter plot and used the equation
𝑦 =11+15𝑥 for the regression line.
What is the meaning of the slope and the y-intercept of this regression line?
