Answer:

y= x -1.25

Step-by-step explanation:

Use slope= y2-y1/x2-x1

(13.75, 12.50), (3.25 , 2.00)

12.50 -2.00/ 13.75 -3.25

10.50/ 10.50

slope= 1

Substitute into y=mx+b

12.50= 1(13.75) +b

b= -1.25

y= x -1.25

Answer:

The projected world population in 2015 was 8,705,121,030 people.

Step-by-step explanation:

Given that the population of the world in 1987 was 5 billion and the annual growth rate was estimated at 2 percent per year, assuming that the world population follows an exponential growth model, to find the projected world population in 2015 the following calculation must be performed :

5,000,000,000 x 1.02 ^ (2015-1987) = X

5,000,000,000 x 1.02 ^ 28 = X

5,000,000,000 x 1.741024 = X

8,705,121,030 = X

Therefore, the projected world population in 2015 was 8,705,121,030 people.
