Answer:
[tex]y = 120\,in[/tex]
Step-by-step explanation:
The points show a high postive correlation with a linear model, whose slope is constant:
[tex]m = \frac{\Delta y}{\Delta x}[/tex]
[tex]m = \frac{20\,in}{20\,weeks}[/tex]
[tex]m = 1\,\frac{in}{weeks}[/tex]
The numerical value predicted by the fit line is:
[tex]y = 20\,in + \left(1\,\frac{in}{weeks} \right)\cdot (120\,weeks)[/tex]
[tex]y = 120\,in[/tex]
