The birth rate in a certain country in 1996 was 15.4 per thousand population. In 2006, the birth rate was 14.49 per thousand. a. Let x represent years after1996 and y represent the birth rate. Assume the relationship between x and y is linear over this period. Write a linear equation in terms of x. b. Use the linear equation from part a to estimate the birth rate in this country in the year 2026
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
