Topic: The relationship between the length of an adult's femur (thigh bone) and the height of the adult can be approximated by the linear equations y = 0.432x - 10.44 (female) y = 0.449x - 12.15 (male) where y is the length of the femur in inches and x is the height of the adult in inches (see figure). y in. Y femur x in. Is there a height for which the length of the femur bones of an adult male and an adult female will be equal? If so, what is that height? If not, explain why not? Explain your reasoning.
