Answer:
-320000
Step-by-step explanation:
Given
Lost Land = 80,000 acres yearly
Duration 4 years
Required
The total change
Represent the total change with y;
y is calculated as thus;



<em>Hence, a total of 320000 acres were lost during the period</em>
We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430
