Question

The model y=a+b/x passes through (2,4) and (4,3). Fit the straight line of y against 1/x, check the further point (8,2.5), and explain what the vertical intercept describes in the original variables.

Accepted Answer

$y=2+4/x$; the further point fits. The intercept 2 is the value approached as $x\to+\infty$.
