A cell’s immune response to an infection depends on a sequence
of chemical mes-
sengers. In researching how such chemical messengers are
transported from outside into the cell,
Rutger D. Luteijn and Shivam A. Zaver et al. measured how folic
acid (vitamin B9) and other med-
ications inhibit the cell’s uptake (absorption) of immunoreactive
chemical messengers [2]. Table 2
summarizes some of their data.

We can cancel the factor and get

(2.4) The value corresponds to the slope of the line passing thought the origin that fits the data the best according to least squares.
