Answer
The slope is $1.62$ (million tons of production) per (1 million acre increase).
(For each million acres increase in area, the production increases by about 1.62 million tons.)
Work Step by Step
The unit of slope in
$y=mx+b$
is (unit of y) per (unit of x)
The slope is calculated as (change in y)/(change in x).
Here, $P=1.62A-23.87$
the slope is $1.62$ (million tons of production) per (1 million acre increase).
(For each million acres, the production increases by about 1.62 million tons.)
