Question 815360: Suppose the growth of population during the period from 1980 to 2008 can be approximated by an equation of the form y = mx + b where x is the number of years since 1980 and y is the population measured in millions. Find the equation if two ordered pairs that satisfy it are (0,223) and (10,249)

Answer:
the slope-intercept equation for the line is:
m = 2.6
b = 223
y = 2.6x + 223
