Scientists measured the annual forest loss (in square kilometers) in a country from 2000 to 2012. They found the regression line

forest loss =7700+ (1029year since 2000)

for predicting forest loss in square kilometers from years since 2000.

(a) What is the slope of this line?

km²

Say in words what the numerical value of the slope tells you.

For each year since 2012, forest loss averages about 7700 km².

For each year since 2000, forest loss averages about 7700 km².

For each year since 2012, forest loss averages about 1029 km².

For each year since 2000, forest loss averages about 1029 km².

For each year since 2000, forest loss averages about 1.029 km².

(b) If we measured forest loss in square meters per year, what would the slope be? Note that there are 10⁶square meters in a square kilometer.

m²

(c) If we measured forest loss in thousands of square kilometers per year, what would the slope be? (Enter your answer to three decimal places.)

thousands of km²
