According to a census there were 65 people per square mile( this is called the population density) in a certain country in 1980. By 2000, the number of people per square mile had grown to 81. Use this information to develop a linear equation in slope-intercept form. In developing the equation, think of 1980 as year zero. Let x be the time in years and let y be the population density. Write a linear equation in slope-intercept form to model the given information. The equation is ?
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.
