The scatterplot below shows students' heights (y) versus father's heights (x) for a sample of 173 college students. The symbol "+" represents a male student and the symbol "o" represents a female student.
A linear regression equation is determined for the relationship between female students' heights and their father's heights and, separately, one for male students and their fathers. How do the y-intercepts compare for these two regression equations?
