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)

the line that passes through (0,223) and (10,249) can be determined by using the two-point form of the linear equation.

plug this:
0, 223, 10, 249
into the Two-Point form: x1 y1 x2 y2 input box here:

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