Question 643537: Ths pertains to a previous question:
A scientist is studying the number of a certain type of bird in his state. He is sure that the number of birds is related to the number of green slugs found in the area which is the bird's favorite prey. After counting both slugs and birds in several areas he finds a linear relationship: Number birds = 0.0035 X (Number of slugs). What does the slope of the line equal?
So the slope is the m=0.0035. What does the y-intercept equal? Or is it unknown? Don't we substitute x=0? to solve for b? The answer choices given were 1 - number of birds, 2 - 0.0035 3-Number of slugs or 4-none of the above?
