Answer:
The slope of this line is 1021.
Step-by-step explanation:
A regression line has the following format:
y = b + ax
In which a is the slope, that is, how much y changes with a variation of a single unit in x.
In this problem, our line is:
forest loss=7500+1021x
In which x is the number of years after 2000.
So the slope of this line is 1021.
