The birth rate in a certain country in 1993 was 14.9 births per thousand population. In 2003, the birth rate was 14.63 births per thousand. Write two ordered pairs of the form (x, y), where x is years after 1993 and y is birth rate per thousand population.
Assume that the relationship between x and y is linear over this period. Use the ordered pairs from part (a) to write an equation of the line relating years to birth rate.
Use the linear equation from part (b) to estimate the birth rate in this country in the year 2023.
