The femur length for someone with height 164cm can be predicted by the nature of the equation of the line.
using the equation of the line in slope format we can get this
[tex]\begin{gathered} \frac{164-150}{y-39}=\frac{150-143}{39-36}=\frac{7}{3} \\ \frac{14}{y-39}=\frac{7}{3} \\ \text{cross multiply} \\ 52=7(y-39) \\ 52=7y-273 \\ 7y=\text{ 325} \\ y=46.4\text{ cm} \end{gathered}[/tex]Therefore the graph predicts a femur length of 46.4 cm for a height of 164 cm
